Copper smelting methods can be divided into two categories: pyrometallurgy and hydrometallurgy. More than 85% of the world's refined copper output is recovered from pyrophyllite concentrates and recycled copper by pyrometallurgical process, and the refined copper produced by hydrometallurgy only accounts for about 15%.
In China, copper metal is extracted from copper concentrates mainly by the pyrometallurgical method. The more advanced one is flash smelting, whose output accounts for over 30% of the total copper produced in the country. Due to low energy consumption, large-scale, can effectively control the advantages of environmental pollution. This smelting technology is being developed in the copper industry. Flash smelting furnace according to different working principle can be divided into two types: Outokumpu flash melting, InCo flash melting. The following describes Outokumpu smelting process.
