Flash smelting has been the most widely adopted copper matte smelting process since 1970. More than 40 furnaces have been installed to replace reverberatory furnaces or at new smelting operations. Nowadays the Outokumpu-type smelters account for more than 50 % of world primary smelter capacity. Processing and Uses

Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

The smelting process typically produces less than three tons of solid waste per ton of copper produced. Pollution Prevention and Control Process gas streams containing SO2 are processed to produce sulfuric acid, liquid sulfur dioxide, or sulfur. The smelting furnace will generate process gas streams with SO2 concentrations ranging 0.5-80% percent

Based on process, the copper smelting market can be divided into reverberatory smelting, oxygen flash smelting, acid plant, tapping-the-flash furnace, converter furnace, and others. Reverberatory smelting and oxygen flash smelting are methods that require the resultant molten copper to be further processed to attain 99.9% pure copper.

There are only a few smelters processing copper concentrates directly into blister copper. Despite the many advantages of this process, a serious challenge of this technology is the need to process the resulting flash smelting slag. It contains 12–15% copper and 2.5–4% lead. In this form, it cannot be considered as waste material and, therefore, a high-temperature reduction process is
