METHOD AND SYSTEM FOR SHORT-PROCESS COPPER SMELTING

WIPO Patent Application WO/2018/228075

A1

A method and system for short-process copper smelting. Copper smelting equipment employed in the method comprise a smelting furnace (10), a copper forging furnace (20), a CR furnace (30), a first flow groove, and a second flow groove. The smelting furnace (10) is provided with a copper sulfide outlet and a smelting slag outlet. The copper forging furnace (20) is provided with a copper sulfide inlet, the copper sulfide inlet being in communication with the copper sulfide outlet via the first flow groove. The CR furnace (30) is provided with a smelting slag inlet, the smelting slag inlet being in communication with the smelting slag outlet via the second flow groove. A copper concentrate is smelted in the smelting furnace (10) to produce a first copper sulfide and a smelting slag; the first copper sulfide undergoes a copper forging reaction in the copper forging furnace (20) to generate an anode copper and a copper forging slag; the smelting slag undergoes reduction, fuming, and settlement in the CR furnace (30) to comprehensively reclaim valuable metals in the smelting slag and to produce a harmless slag.
