WebOne method is to melt them with fluxes in a smelter furnace to produce copper matte, which is a mixture mainly of iron and copper sulfides usually containing 50 to 70% copper. The molten matte is poured into a converter, which contains more fluxes and converted into blister copper, which is about 98 to 99% pure. WebCopper was initially recovered from sulfide ores by directly smelting the ore in a furnace. [9] The smelters were initially located near the mines to minimize the cost of transport. This avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the copper-containing minerals.
