The Bingham Canyon Mine contains veins of copper sulphide, so the ore extracted contains sulphur, which needs to be separated from the copper. The smelting process breaks elements apart and sulphur is driven off as sulphur dioxide gas. Kennecott's smelter is one of the most modern and cleanest in the world.
Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process.
The smelting process: from ore to pure copper. Flotation is a physicalchemical process which allows the separation of hydrophobic materials. Concentrated dry copper ...
Smelting involves more than just melting the metal out of its ore. Most ores are a chemical compound of the metal with other elements, such as oxygen (as an oxide), sulfur (as a sulfide) or carbon and oxygen together (as a carbonate). To produce the metal, these compounds have to undergo a chemical reaction.
Smelting. Copper smelting involves three steps: Roasting: First, ore concentrates are roasted or heated to remove sulfur and moisture. Smelting: Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturallyseparating layers.

Ore Smelting. In nature, the ores of metals such as iron, copper, lead, aluminum and othe metals are found impure states, often oxidized and mixed in with silicates of other metals. During smelting when the ore is exposed to high temperatures, these impurities are seperated from the molten metal and can be removed.
The ore was crushed to smaller pieces, in order to create more surface area, speeding up the smelting process in the furnace. The chemical principles of smelting copper ore. The chemical formula of malachite is Cu2CO3(OH)2. This means that it's a carbonate, where the copper is bonded with carbon and oxygen (plus chemically bonded water).
Environmental Guidelines for Copper Smelting ... process the ore is leached with ammonia or sulfuric acid to extract the copper. These
Copper Production ; Copper Facts ... The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.
