METHOD FOR PROCESSING OF SILVER-BEARING MANGANESE ORES

摘要

FIELD: nonferrous metallurgy, silver extraction. SUBSTANCE: method for processing of silver-bearing manganese ores includes manganese mineral stripping and leaching of silver; both processes are carried out simultaneously by acid solution of iron sulfate; silver is extracted from the leached product by flotation. The flotation tailings are dehydrated; manganese is extracted from the solution; the regenerated acid solution of iron sulfate is recirculated. EFFECT: increased efficiency of the process. 2 cl
