Side-blown smelting furnace process: copper sulfide concentrate, together with flux and auxiliary materials, is charged into the molten bath. Oxygen-enriched air is introduced through tuyeres on both sides of the furnace body, agitating the bath and creating strong turbulence. This rapidly completes sulfide ore oxidation and slag formation, with the smelting temperature controlled at 1150°C to 1250°C.
The produced matte is intermittently discharged through the siphon outlet and sent to the converter for subsequent converting. The main bath area can be lined with standard magnesia-chrome bricks. The tuyere area and slag line are key high-wear zones of the furnace lining, where operating conditions are more severe, so high-grade magnesia-chrome bricks are recommended for coordinated installation.
