DRY-TYPE TREATING METHOD AND SYSTEM FOR CONVERTER SLAG IN COPPER REFINING

摘要

PROBLEM TO BE SOLVED: To provide a system for converting slag exhausted from a converter in copper refining into an ironmaking raw material.SOLUTION: In a treating system for converter slag generated in a copper-refining process, the system is provided with: a reducing furnace for heat-reducing a zinc content and copper content contained in the converter slag and also for heat-reducing FeOcontained in the slag into FeO; a gas-exhausting means, arranged in the reducing furnace for removing a reduced zinc that is volatilized; a settling furnace for sink-separating the reduced copper from the slag; a molten material trough for shifting the exhausted slag from the reducing furnace into the settling furnace; and a crude-copper trough for taking out the sink-separated reduced copper from the settling furnace.
