2021 TMS Annual Meeting & Exhibition: High Temperature Electrochemistry IV: Organized by Prabhat Tripathy; Guy Fredrickson

High-temperature electrochemical processes are known to be technically challenging and yet technologically rewarding. Over past several decades, these processes have been deployed in many capital-intensive-power-generating industries, such as nuclear, fossil-fuel and geothermal. Besides, these processes are being routinely designed to synthesize advanced engineering materials and recover critical elements from a diverse range of waste materials. A resurgent interest in the arena of advanced nuclear reactor technologies has generated fresh impetus to the development of molten salt technologies. Exciting research results in used nuclear fuel reprocessing, fossil energy conversion, reversible fuel cells, gas separation and purification, emission(s) reduction, inexpensive materials manufacturing and recycling are being increasingly reported. The organizers feel that the time is now appropriate to hold the fourth biennial symposium, titled, “High Temperature Electrochemistry IV” in 2021 to discuss some of the recent advancements made in the field of materials electrochemistry. Topics covering all aspects of molten salt electrochemistry are being solicited. Specific topics include, but are not limited to, science and technology of molten salts as well as oxides, synthesis and characterization of advanced materials, molten salt electrowinning/refining, materials recycling, performance characteristic of nuclear/structural materials in nuclear reactors and electrolyte chemistry as applicable to molten salt rector technologies and used nuclear fuel reprocessing.

2020 TMS Annual Meeting & Exhibition: PbZn 2020: The 9th International Symposium on Lead and Zinc Processing: Organized by Andreas Siegmund; Shafiq Alam; Joseph Grogan; Ulrich Kerney; Cheng Liu; Etsuro Shibata

The Lead – Zinc 2020 symposium builds on the successes of the original 1970 meeting, the subsequent conferences held in 1980, 1990, 2000 and 2010, the Zinc – Lead symposia in Japan organized by MMIJ in 1995 and 2005, the Lead-Zinc conference in Germany by GDMB in 2015, as well as the Canadian Lead – Zinc conferences organized by MetSoc in 1998 and 2008. It will provide an international forum for the lead and zinc processing industries bringing together operators, engineers and researchers to exchange information about all aspects of current processing technologies for primary and secondary lead and zinc, as well as emerging technologies for both metals. The symposium scope extends from process fundamentals to operational practices, and also includes the important aspect of environmental issues. At the operations level, comprehensive reviews of the major applications of both metals are outlined. Emphasis will be placed on recent commercial developments with less energy intensive technologies which are in harmony with environmental conservation. At the research level, the emphasis is placed on the better understanding of existing technologies and the development of new processing concepts. Environmental concerns, associated with the processing of both metals, are considered along with acceptable treatment and handling of by-products, wastes and bleed streams by the industry. A highlight of the conference will be a series of plenary lectures by industry leaders. Various social events are scheduled, and these will allow informal discussions and networking among the delegates. After the symposium, industrial tours are planned to various North American lead and zinc processing operations. Topics to be discussed at the symposium include: * Global factors affecting the production of zinc and lead including the economic aspects of the industries, product development and marketing endeavors, and environmental and health issues, * Surveys of existing smelters and refineries for primary and secondary lead and zinc production, * Zinc production technology (roast-leach-electrowinning route including iron control, pyrometallurgical processes, ISP, slag fuming, Waelz furnace, TBRC and new technologies including direct concentrate leaching and smelting, pyrometallurgical refining and oxide ore processing), * Lead production technology (pyrometallurgical processes such as the ISP, blast furnace, QSL, KIVCET, SKS-RSKS and TSL, as well as pyrometallurgical refining, electrorefining, slag fuming and new processes), * Product applications and marketing (galvanization of steel, chemicals, ZnO, lead-acid batteries) and new product development, * Recycling technologies and product life cycle issues (e.g. electric arc furnace dust treatment and direct de-zincing, secondary lead processing), and * Fundamental research and basic studies related to new Pb and Zn processes and to the understanding and basic theories of Pb and Zn processing.

2020 TMS Annual Meeting & Exhibition: Electrometallurgy 2020: Organized by Antoine Allanore; Michael Free; Georges Houlachi; Hojong Kim; Takanari Ouchi; Shijie Wang

Electrolytic processing is used commercially to recover and/or refine metals including large–scale production of aluminum, copper, magnesium, nickel, and zinc as well as, on a smaller scale, for recovery and refining of gold and silver. There are also exciting opportunities to utilize electrometallurgy in the production of titanium, lead, and other metals. Electrolytic processing of metals faces common challenges that include energy utilization, chemistry, productivity, and safety. To meet the present challenges in commercial electrometallurgy, a variety of technological advances have been made. Similar challenges will be faced in the future, requiring process improvements and innovations. The 3rd International Symposium on Electrometallurgy – building on the success of Orlando 2012 and Quebec City 2016, will bring together industry, consulting engineers and researchers to discuss fundamental research, development, and/or application of innovative aqueous or molten salt electrometallurgical processing technologies for the extraction of metals. The Symposium will provide a forum for the international metallurgical community to discuss innovative approaches to reduce the energy consumption during electrolysis of metals. This Symposium is organized by TMS and Met Soc, with the leadership of the TMS Extraction and Processing Division, with support from the Hydrometallurgy and Electrometallurgy, Process Modeling and Technology, and Pyrometallurgy Committees.
