The Outlook for Silver Investment

Philip Newman, Thomson Reuters GFMS Philip Newman is Research Director at Thomson Rueters GFMS, focusing on the gold and silver markets in the United States, the United Kingdom and a number of other European countries plus the key Middle Eastern markets of Turkey and Egypt. Philip holds an Honours degree in Economics from the University of Surrey in England. He joined GFMS in January 1994. Abstract Last year, against a backdrop of a widening market surplus, silver prices continued to rise, with annual average prices setting a fresh all-time high. The chief reason for this was the growth in world silver investment, which posted a record total in value terms. This occurred even though periods of volatile silver prices led to bouts of heavy investor liquidations. Looking ahead to this year, with the global surplus in the silver market forecast to grow once more, will we see investors step in to absorb the excess metal as they have done so in recent years? And if so, what are the implications for silver prices? Philip Newman, Research Director at Thomson Reuters GFMS, will address these questions in his presentation entitled “The Outlook for Silver Investment.”

Mike has worked and consulted for major metallurgical research organizations and metals operations in the USA, South Africa, Europe, and Canada. When he is not consulting, he is an Assistant Professor in the MBA program at Franklin Pierce University, New Hampshire. Abstract Precious metals feedstocks normally contain a host of contaminant metals, such as Hg, Cd, As, Se, etc. that are often referred to as deleterious elements due to their health and environmental hazards and the challenges of handling these materials. Of the deleterious elements, mercury is often the most difficult to deal with as trace amounts are found in many refining feedstocks and its discharge in effluents is highly regulated. This paper serves to review the background and origins of mercury in refining feedstocks. Mercury detection approaches are examined and a review of the chemistry of mercury in refining circuits is presented. Finally the present state of the art in mercury treatment, handling and recovery is examined.

Speciation and Quantification of Platinum-Chloro Complexes Using Ion Exchange Chromatography and Inductively Coupled Plasma Mass Spectrometry

Kwan Nam, BASF Corporation Dr. Kwan H. Nam is a staff chemist and a supervisor to the instrumentation section of the Precious Metals Assay Services group at BASF Catalyst in Union, NJ. He received a B.S. degree from Worcester Polytechnic Institute, and M.S. and Ph.D. from Syracuse University all in Chemical Engineering. Prior to joining BASF, he was a laboratory manager at Evans Analytical Group, and a research scientist at GE. Abstract Trace levels of precious metal elements can find importance, especially as the value of these metals increase and much attention has been received from the manufacturing, recycling and environmental sectors. Speciation and quantification of trace levels of these precious metal elements, particularly for platinum, are performed by ion-exchange chromatography (IC) with UV absorption detection and inductively coupled plasma-mass spectrometry (ICP-MS). There are only a few published papers that examine the use of IC as stand alone technique or combined with ICP-MS for the separation and quantification of precious metals. The analytical procedure used and the results found are presented and discussed. Clear separation of the precious metal species was demonstrated along with high sensitivities down to ultra trace levels. This technique and the method used in this work show applicability towards speciation and quantification of trace levels of precious metals in materials such as automobile catalyst samples.

 The Principles of Micro-XRF in the Jewelry Business

Robert Erler, Bruker Robert Erler is Application Scientist/Product Manager at Bruker Nano Gmbh in Berlin, Germany. He is responsible for testing, improving and managing XRF Instruments. He received a Master Degree in Physics at the Technical University of Berlin. Abstract Bruker will present the principles of Micro-XRF in the field of jewelry business. Increasing precious metal prices are demanding the fast and non-destructive analysis of elemental composition with XRF all over the world. But reliable analysis requires more than the average bulk composition with the “first shot.” Inhomogeneity, surface structure and shape will impact the result.

 CEIA Presentation

Nick Belenky,CEIA Nick Belenky is an expert in loss prevention of precious metals through computer aided metal detection. He works as a Sales Engineer for CEIA (pronounced CHAY-YUH) to consult with suppliers of precious metal products on improving their personnel screening procedures and equipment.

Inventory Valuations-Where’s My Metal?!?!?!

Bill Tierney, Computer Associates Inc. Bill Tierney manages the Computer Associate’s Precious Metals Refining vertical and the development staff of the company’s industryleading Navision for Refiners refining software. Bill’s team is responsible for all aspects application installation, training, modification deployment and support. The Navision for Refiners product, based on Microsoft’s Dynamics NAV software, is a 100% Windows-based Enterprise Resource Planning (ERP) solution that streamlines the refining and settlement process and includes integrated back-office applications such as General Ledger, Accounts Payable, Accounts Receivable and additional software modules optimized for metals processors. Bill and his team have completed a range of Microsoft-sponsored Dynamics NAV training programs and are fully certified in the Microsoft Dynamics NAV technology suite. Abstract Tracking precious metal inventory within a refining operation is both art and science. Estimating precious metal content on customer lots before lab results are known or the lot is settled is as much art as it is science. Tracking Inventory and its precious metal content after lab results are known brings together the sciences of Inventory Control and precious metals Inventory Management. The effective management of precious metals stock requires a thorough understanding and reporting of where and in what state the inventory is in. We will take a look at the components and the process involved in analyzing and reporting precious metals inventory.

 The 4 Eye Security Principle in Paperless Environments

Peter Schmitt, BASIQ Peter Schmitt has extensive experience in both academia and industry. He started out with a study of physics at the University of Wuerzburg, Germany. He did his PhD at DESY (Deutsches Elektronen Synchrotron) in Hamburg and work at CERN (Geneva) as a postdoctoral research assistant for Harvard University. He went into industry starting as project manager for the development or car phones at AEG in Ulm. In 1995 he moved to the United States to work for BASF in various IT positions, among them Director of Infrastructure in the US and Project Leader for SAP implementations. In 2003, he founded his own company Schmitt & Associates, LLC. The company provides a range of IT products; among them are webbased database applications as well as reporting and analysis tools for business processes.Since 2010 Peter Schmitt has additional responsibilities as IT director for BASIQ Corp. He currently develops new software approaches to manage precious metals business processes. Abstract The “four-eye principle,” the concept of always having two people sign off on weight recordings for precious metals, is still regarded as one of the most effective control features in our industry. Paperless weight recording systems (= scales connected directly to an IT system) create the need to also record the “four-eye” sign-off or handshake electronically, and to embed the information with each transaction in a secure manner. This paper introduces various technologies to accomplish this from a process point of view, and it gives an insight into universal ways of implementing the method into any ERP or business management software.

She is responsible for the coverage of the precious metals markets, specifically gold, silver, platinum and palladium, for Barclays Capital’s suite of commodity research publications. She is also involved in the team’s regular analysis of commodity investment flows and the growth of commodities as an asset class. Ms. Cooper joined Barclays Capital in 2004 and the Commodities Research team in 2006. Prior to joining Barclays Capital, she was a chartered accountant at PricewaterhouseCoopers LLP (2001 – 2004). Abstract We expect the dominant macro trends this year to be improving global growth momentum, stronger business confidence and a resurgence of longer term inflation expectations as policymakers focus on growth. Although the macro environment continues to be clouded by uncertainty, it is one that should be supportive of precious metals price gains. However, we believe the outlook for prices across the complex will be closer in tune to individual market dynamics. Can gold prices continue to extend their gains as investment demand slows? Will platinum remain in surplus for a second year given recent supply disruptions. We believe gold can retain its premium over platinum for a little longer yet.

Oxide Dispersion Hardened Platinum Alloys with Improved Strength at High Temperatures

Bernd Fischer, University of Applied Sciences, Jena Bernd Fischer is professor for materials science at the University of Applied Sciences Jena, Germany. Bernd Fischer studied materials technology at the Technical University Chemnitz, Germany and received his doctorate degree in 1971. After that he started to work in the field of high temperature materials, especially platinum group metals, at the University in Jena. In 1992 Bernd Fischer was awarded the chair of materials science at the University of Applied Sciences Jena. He was dean of the Faculty of Materials Technology from 1992 to 1994 and Pro-Rector for Research at the University from 1994 to 1997. Over many years his research topics have included studies of the properties and applications of noble and refractory metals. During the last years his research has focused on the development and characterization of platinum alloys, especially oxide dispersion hardened platinum materials. After his retirement in 2006 he has worked on his research topic until 2012. Abstract More than ten years ago, dispersion hardened platinum alloys with nano-oxide particles (Pt DPH materials) were developed with improved properties. Today these materials are being used very successfully in industry, especially in glass melting equipment for high temperatures. After a short introduction to the structure (TEM micrographs), properties and examples of application of the Pt DPH materials, this paper reports on the further development of these materials to achieve even higher stress rupture strength. The better strength is achieved by higher contents of nano-oxide particles. Despite its much higher strength the material can be readily rolled to thin sheets and processed to seamless tubes. A further increase in strength can be obtained by thermo-mechanical treatment. The mechanical properties of the improved Pt DPH materials are characterised in creep tests and hot tensile tests at temperatures from 1,200 °C to 1,700 °C. Special equipment to test samples at temperatures from 1,000 °C to 3,000 °C has been developed by the University of Applied Sciences Jena for mechanical investigations of this type. The mechanical properties measured in creep tests (stress-rupture strength, creep-strain limits, rupture strain, Norton’s creep law) and in hot tensile tests (0.2 % yield stress, tensile strength, rupture strain) are discussed in connection with microstructural investigations (metallographic examination of the crystal structure, scanning electron microscopy of fracture surfaces). The fracture propagation of samples is presented in video sequences. The distribution of the nano-oxide particles is shown in micrographs obtained by scanning secondary ion mass spectroscopy. The new Pt DPHhs materials are compared with previous materials. The newly developed materials have higher strength and better form stability. This permits a longer service life to be attained with highly stressed components in glass melt technology.

Best Practice in Silver Refining - HSSE Bulk Material Electroylsis Technology and Closed Loop Processing of Spent Silver Electrolyte

Joachim Prior, Prior Engineering Joachim Prior gained a BSc. in “Chemical Engineering” followed by a MSc. in “Process and Plant Engineering” in 2000 at Graz Technical University (TU Graz), Austria. He joined the Prior Engineering Group already during his thesis in 1999, where he prototyped an online UV detector for Continuous Annular Chromatography units. As a Project Manager Joachim was first continuing on specific annular chromatography development topics. Long-term sterility, Design Qualification in cooperation with strategic partners from “big pharma” in US and Europe, launch of the company’s first European CRAFT research project were some of the achievements. In 2004, the Prior Engineering Group was rearranged and Joachim was promoted as Technical Director. Apart from the regular duties of customer project settlement, he has been responsible for the re-engineering and enhancement of the various precious metal technologies developed by Prior Engineering during the 1990’s but also for new developments focusing on the precious metal refining market. Abstract Bulk material electrolysis (following the Moebius Principle) like the HSSE imply more than simply using granules to build an anode instead of conventionally case anodes. Apart from clear electro-chemical advantages and zero anode return, there are several other aspects to be considered for silver refining overcoming numerous limits of conventional Moebius processes. Proper bulk material electrolysis technology allows online extraction of anode slime resulting in fast access to the gold and palladium without interrupting the electrolysis cell production at all. Conventional processing of spent silver electrolyte often resulting in a typical impurity cascade requiring several controlled process steps. Technical aspects of such a modern silver refining strategy and several key figures and specifically required silver refining technology will be pointed out.

Sustainable Recycling of Precious Metals

Steve Izatt, IBC Advanced Technologies Steven Izatt has over 20 years experience in the development and management of high technology businesses in the separations, chemical, metallurgical and engineering industries. As President of IBC, he has worked extensively in supplying Molecular Recognition Technology separation systems to major corporations worldwide that use and refine precious metals. He holds two Ms degrees from MIT, one in Chemical Engineering Practice and the other in Technology and Policy and received his Bachelor’s degree from Brigham Young University. He is the 2008 Recipient of the IPMI Junichiro Tanaka Distinguished Achievement Award. Abstract Precious metals constitute a valuable economic resource, especially in electronic and catalytic products. Despite the presence of these high-value resources, there is little actual recycling.In order for the recycling of these materials to be sustainable, the process must not only be economic, but must cleanly, safelyand efficiently separate low levels of precious metals from difficult matrices. This must be done in an environmentally sound manner, without adding any contaminants during processing,with minimal energy usage, at strategically located facilities to promote recycling, and with a comprehensive approach that maximizes the recovery or reuse of substrates, base metals, and precious metals. This paper will discuss the use of highly selective Molecular Recognition Technology (MRT) in achieving the sustainable recycling of precious metals with relatively low capital investment.



Gold Processing Technology at Montana Tech

Nick Gow, Montana Tech Robert (Nick) Gow received his B.S. and M.S. in Metallurgical Engineering in 2008 from Montana Tech. He is currently an interdisciplinary PhD candidate at the University of Montana. He was a 2011 IPMI Student Award winner. His graduate work has focused on several aspects of gold processing technologies. Abstract Two projects, examining different areas of hydrometallurgical processing of gold, were undertaken over the last few years at Montana Tech. The first looked to understand and maximize the conditions for treating gold thiosulfate leach liquors with copper cyanide-loaded activated carbon. The end result was a novel gold thiosulfate solution recovery process that allows for high gold extraction followed by traditional elution. The second project is ongoing, and takes a fundamental approach to understanding enargite (Cu3AsS4) processing. The presence of enargite is problematic in gold processing as it is refractory, increasing cyanide and oxygen consumption, and environmentally hazardous. Selective leaching and treatment of the arsenic would prove advantageous to conventional gold leaching methods. The reactivity of enargite samples from Montana, US and Quiruvilca, Peru were studied under acidic and alkaline conditions using a cyclic voltammetry corrosion cell setup. Raman spectra of the surface were taken during and after cycling to compare surface species against theoretical predominance diagrams

Palladium and palladium alloys are critical to such membranes, and the Center for Advanced Mineral and Metallurgical Processing is developing a membrane based on autocatalytic reduction of palladium from solution onto a unique substrate. Additive manufacturing methods produce the base substrate which is then bridged with microspheres and polymerized. Palladium alloys are reduced onto the surface to form a comprehensive and robust hydrogen filtering medium of ideal morphology.



Recycling of Precious Metals: A Sustainable Contribution to Resource Efficiency

Viren Pathare, Heraeus Precious Metal Processing Dr. Viren Pathare is the Sales Director for Recycling Business Unit of Heraeus Metal Processing located in Santa Fe Springs, CA and Wartburg, TN. Prior to joining Heraeus in 2007 Viren worked in the semiconductors, opto-electronics and specialty materials industries Abstract Refining is a critical step in the life cycle of precious metals. Without refining, the availability of precious metals would decrease and the price would rise to uneconomical levels. The energy used and the carbon dioxide emissions in refining are a fraction of what primary mining would entail. The Precious Metals Refining Industry continues to invest and innovate in order to recycle diverse streams containing precious metals while continuously reducing the impact on the environment. This presentation will show specific examples of innovations and investments undertaken by Heraeus Precious Metals NA to serve the needs of mining, catalysts, electronics and jewelry/dental industries. One important goal of our investments, in our Santa Fe Springs, CA location, is for environmental stewardship. We will describe how Heraeus has gone above and beyond compliance requirements to be a good neighbor and industry leader.

He participated and spoke at over 20 national and international conferences. He is a member of Scientific Council of Institute of Non-Ferrous Metals. Abstract In this work investigation results of innovative silver based material have been presented. Microstructure and properties of new silver alloy with addition 1% of mishmetal (mixture of rare earth metals) designed for electric contacts applications were shown. Material processing included melting and casting in vacuum furnace, extrusion by severe deformation technique (KOBO® method) and drawing. Obtained wires were used for production of electric contacts which were designed for exploitation tests comparing to the actually produced AgNi0,15 electric contact material. Ag+1% of mishmetal alloy had better mechanical properties then AgNi0,15 alloy after plastic deformation and after annealing. Silver –mishmetal alloy revealed advantageous properties as an electric contact material. Comparing to the AgNi0,15 alloy it had 3 times lower mass loss of electric contacts. New material revealed also lower contact resistivity during electric contact tests. Microstructure and mechanical properties of this material are stable at elevated temperature and its electrical conductivity is also favourable. Demanded characteristic has been obtained by rare earth metals alloy additive combined with severe plastic deformation. During processing dispersion and precipitation hardened fine grained microstructure has been observed using optical and electron scanning and transmission microscopy.

In this paper experiences at Duesmann & Hensel will be presented, in particular comparisons of XRF results with the results of wet chemical analysis.

 Importance of an Appropriate Procedure for Moisture Determination to Obtain Accurate Metal Content in Different Types of Precious Metal Containing Materials

Dirk Hofmanns, Umciore Dr. Hofmans studied at the University of Antwerp and holds a PhD in chemistry on precious metals coordination compounds. He began at Umicore in 1986 when they were called MHO. He has been involved in precious metal analysis since 1987. Since 1993 he has been responsible for the precious metal section of the analytical laboratory at Hoboken, Belgium. Abstract It is important in an assay exchange procedure between the refiner and the supplier of precious metals bearing products that the basis, on which the precious metal content of a sample is determined and reported, is clear, accurate and reproducible. Moisture is one of the factors that can have a strong influence on the reported analytical results on dry state, especially with hygroscopic materials or materials with components that can be lost at temperatures close to the boiling point of water. This also counts for the way a net dry weight is determined in the sampling process. Different techniques are available today to determine moisture. These techniques are classical drying ovens and desiccators to prevent moisture pick up during cooling down to room temperature, infrared moisture balances and also more sophisticated thermogravimetric techniques. In our presentation we want to make an overview of the strengths and weaknesses we experienced with these different techniques at Umicore Precious Metals Refining. We will illustrate the specific case of anodic slimes and potential risks if moisture is determined by the different moisture techniques at the standard drying conditions.
