Beschreibung
Zusammenfassung:	The invention relates to a comprehensive utilization process of molten copper slag and a system thereof, which has the characteristics of high extraction ratio, low cost, energy saving, and the like. A feed end of a copper extracting furnace is connected with thermal molten copper slag, the copper extracting furnace is also provided with a spray gun, and the tail end of the spray gun is immersed in a molten pool. A slag outlet of the copper extracting furnace is connected with a feed end of a copper iron alloy extracting furnace through a feeding device, and CaO is added into the copper extracting furnace through a charging bucket. The copper iron alloy extracting furnace is also provided with a reducing agent II steam addition spray gun, the tail end of the spray gun is immersed in the molten pool, and the bottom of the copper iron alloy extracting furnace is provided with a pure oxygen blow gun. The copper iron alloy extracting furnace is provided with a copper iron alloy discharge port and a waste slag dis
