Title: COMPARISON OF METHODS FOR RECOVERY OF VALUABLE COMPONENTS FROM METALLURGICAL SLAG
Abstract: ABSRACT The slag from lead-zinc metallurgy bears valuable components and its processing raises an increasing interest both from economic and environmental point of view. Low concentrations of metals and metals’ presence as compounds different from natural minerals are the major obstacles in applying classical mineral processing technologies for metals’ recovery. The paper compares results for copper extraction by application of different mineral processing technologies (hydrometallurgy, magnetic separation, classical flotation, electrochemically aided flotation, flotation of electrochemically pre-enriched material). Best results are obtained by electrochemically aided sulfide flotation, applied to electrochemically pretreated slag.
