Arsenic has long been a problem associated with the extraction ofnonferrous metals. During the last decade, a combination oflower-grade ores and environmental concerns has resulted inaccelerated technological developments to meet arsenic challenges.This volume presents the necessary technologies to further advancearsenic metallurgy. Treatment of high arsenic-containing ores andmetallurgical streams and wastes are given particular attention.Arsenic metallurgical reactions, process, and environmentaltechnologies are also reviewed. From 2005 TMS Annual Meeting to be held in SanFrancisco, February 13-17, 2005.
