Description

The Extractive Metallurgy series is devoted to the extraction of metals from ores and other sources, their refining to the state of either liquid or solid metal, and the various processes needed to carry out these operations. Using the methodology of chemical reaction engineering, this second volume in the series examines on the metallurgical reaction processes used in the extraction and refining operations, covering pyrometallurgical, hydrometallurgical, halide, and electro-metallurgical processes. It provides valuable information on the technologies and processes engineers encounter in industrial production.
