[0007] This new process is used in the beneficiation of a variety of mixed slags. The properties of the three slags are as follows:
[0008] 1. The flash furnace is the slag produced by smelting copper concentrate through the flash furnace. The nature of the slag is related to the copper concentrate entering the furnace and its large components as well as the smelting operating conditions. The main components are copper sulfide, metallic copper, olivine, iron oxide, ballast, ferrous glass, etc. Slag composition: Cu 2%, Fe 40%, SiO2 28.5%.
[0009] 2. Converter slag is the slag produced by the smelting of copper matte, and its properties are determined by the composition of the copper matte, the smelting operation bar and the cooling rate of the slag. The main ingredients are iron, olivine, magnetite, white matte and matte. Slag composition: Cu 5%, Fe 44%, SiO2 22.0%.
[0010] 3. The depleted electric furnace slag is the slag produced after the copper concentrate is smelted in the ...
