Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

A copper smelting process is disclosed in which copper concentrate is smelted in a furnace to produce purified copper. Flue gas discharged from the furnace is treated to produce sulfuric acid. Furthermore, waste liquid discharged during the production of sulfuric acid is treated to produce gypsum, and the gypsum thus produced is recycled to the furnace as a flux.

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

Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at 0.3-3%. The slag may also contains lead & zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.

The Welsh Process. The Welsh Process of extracting and refining copper was long, costly and tedious when compared with modern techniques, but it remained more or less unchallenged until the mid-19th Century. In 1851, the year of the Great Exhibition, considerable improvements in the smelters were announced; but it was not until Bessemer''s

Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore

Smelting. The process of smelting is a form of extractive metallurgy, meaning its main use is to separate a base metal from its ore. Still used in metal production today, traditional smelting required a heat source and a chemical reducing agent to decompose the ore, usually a source of carbon like charcoal or coke.
