The Lead-Zinc Component of the 2000 TMS Fall Extractive Meeting

The Minerals, Metals & Materials Society's (TMS's) 2000 Fall Extraction and Process Metallurgy Meeting: New Technologies for the Next Millennium (Combining Lead-Zinc 2000 and Recycling of Metals and Engineered Materials), will be held at the Pittsburgh Hilton Hotel, in Pittsburgh, Pennsylvania, from October 22-25, 2000. The Pittsburgh Hilton Hotel is located in downtown Pittsburgh, across from historic Fort Pitt. It provides the ideal location for the TMS Fall Extraction and Process Metallurgy Meeting, which combines two of TMS's popular series meetings—Lead-Zinc 2000 and Recycling of Metals and Engineered Materials. The constituent symposia will coorganize sessions related to the recycling of lead and zinc.

LEAD-ZINC 2000

Lead-Zinc 2000 is the fourth decennial symposium organized by TMS that is devoted to the theory and practice of the extractive metallurgy of lead and zinc. Building on the successes of the original 1970 symposium and the subsequent meetings held in 1980 and 1990, Lead-Zinc 2000 will bring together plant operators, engineers and researchers to discuss all aspects of the hydrometallurgical, electrometallurgical and pyrometallurgical processing of these commercially important metals. At the operations level, the intent is to outline benchmarking technologies as well as present plant operations and recent commercial developments. At the research level, the emphasis will be placed on the understanding of existing technologies and the development of new processing concepts. Environmental concerns associated with the processing of both metals will be considered, along with the acceptable disposal of the various slags, residues and bleed streams produced by the industry.

T.R.A. Davey Dr. Davey obtained his D.Appl.Sc. degree from the University of Melbourne, Australia.

He has also been a professor of metallurgical engineering at the Colorado School of Mines and the University of Melbourne. During his distinguished career, he has consulted for many of the world's leading metals producers and has contributed significantly to the professional administration of the University of Melbourne. In addition to his organization of the first TMS decennial Lead-Zinc meeting, he helped establish the International Hofmann Prize Consortium and served on numerous organizing committees for Australian and international conferences. His many honors include the President's Medal of the AusIMM and the TMS Extractive Metallurgy Division (EMD) Gold Medal Award and was 1988's EMD Lecturer.

SHORT COURSES

A one and one-half day short course will be held on Saturday, October 21 and Sunday, October 22, immediately before the actual symposium. The short course will emphasize the fundamental aspects of the extractive metallurgy of lead and zinc, and will complement the presentations given in the symposium itself. In effect, the short course will review the fundamental basis for the technologies now used by the industry and will offer a foundation for the development of new processes. The Short Course will be divided into a Lead Session and a Zinc Session, which will run concurrently. For either option, a 12-h lecture program will be offered. An outline of the Short Course is given below:

Participation is limited and is on a first-registered, first-accepted basis. Each participant will receive a copy of the short course notes, which will be available only at the short course itself. The notes will be an invaluable reference on the fundamentals of the processing of lead and zinc.

Note:The symposium reserves the right to cancel the short course if the registration is inadequate; a full refund will be provided in such circumstances.
