METHOD OF OBTAINING ELECTROLYTIC MANGANESE FROM FERROALLOY PRODUCTION WASTE

摘要

The invention relates to a method of obtaining electrolytic manganese from sludges resulting from the cleaning of gases that are released by ferroalloy production furnaces, having a high manganese content, using a process comprising the following steps: sulphation, leaching, purification, conditioning and electrolysis. The aforementioned process produces a manganese sulphate liquor which can be used for the already-known electrolysis process in order to obtain electrolytic manganese.
