DescriptionArsenic has long been a problem associated with the extraction of nonferrous metals. During the last decade, a combination of lower-grade ores and environmental concerns has resulted in accelerated technological developments to meet arsenic challenges. This volume presents the necessary technologies to further advance arsenic metallurgy. Treatment of high arsenic-containing ores and metallurgical streams and wastes are given particular attention. Arsenic metallurgical reactions, process, and environmental technologies are also reviewed.
