Abstract
Description
[0001] 1. Technical field: non-ferrous metal metallurgy. 2. Background technology:
[0002] As is known, the smelting method of copper-nickel sulfide ore flotation concentrate is still mainly the pyro-process matte smelting enrichment method. According to the different components of copper-nickel sulfide concentrate, it usually needs to be pre-smelted or sintered to remove part of the sulfur and improve the physical and chemical properties of the charge, and then conduct matte smelting at a high temperature above 1350°C to obtain low matte, which can be called low nickel matte and copper Nickel matte. Roasting equipment includes rotary kiln, melting furnace, shaft furnace, multi-hearth furnace and fluidized melting furnace; melting equipment is mostly blast furnace, reverberatory furnace and electric furnace. In recent years, modern large-scale copper and nickel metallurgical enterprises have introduced new equipment such as flash smelting furnaces and Isa smelting furnaces t...
