About regularities of cobalt chloride distillation process from pyrite concentrate cinders

Abstract

Pyrite concentrates obtained from the beneficiation of many polymetallic ores usually contain, in addition to iron and sulfur, small amounts of cobalt, copper, zinc, lead, nickel and other metals. When using these concentrates for the production of sulfuric acid extracts the bulk of sulfur, and the resulting cinders are on the content of iron in them are industrial ore. In view of the low content of non-ferrous metals, the usual methods and schemes used in obtaining these metals from rich ores cannot be used for their extraction.
