The determinants of the metal recovery of copper smelted in a reverberatory furnace

The metal recovery of reflector smelting mainly depends on the slag rate and slag containing copper, the smoke and dust composition and quantity coming out with furnace gas, the metal content in raw materials and the ice copper grade. Generally, about 97% of copper entering the copper ice. In the loss of copper, copper content in slag accounts for 1.7%, soot accounts for 1%, management loss accounts for 0.3%, and the proportion of slag and copper is about 1.4. [...]
