2020-08-10· Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. A typical process might begin with grinding of the ore into a powder. This powder is processed with chemicals and air to separate out some of the unwanted material and concentrate the copper.

The Basics of Copper Mining and Processing Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. The slag forming reaction is: FeO + SiO 2 → FeO.SiO 2

Pressure Oxidation: All copper minerals are oxidized into an acid-soluble solid (basic copper sulphate). Example: Oxidation of chalcopyrite (6CuFeS 2 + 7.5O 2 + 2H 2 SO 4 + 2H 2 O -> 2[CuSO 4 2Cu(OH)2] + Fe 2 O 3 + 12S°) The sulphur and the hematite (Fe2O3) solids do not leach or react in the subsequent stages of the CESL Process and are disposed of in their current forms as tails.
