Copper extraction - Wikipedia

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

Copper Ore - an overview | ScienceDirect Topics

The principal copper ore mineral is chalcopyrite (CuFeS2 ), which is commonly smelted to yield a matte containing 50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the CuFeSO system at 1 atm SO 2 as a function of temperature ( Rosenqvist 1978 ).

Copper - ore, iron, ores, blue, oxide, obtained, employed

In the extraction of C. from its ores, the metallurgic processes followed are very tedious and complicated, which mainly arises from the difficulty of separating the iron and sulphur from the copper. The general principle which regulates the working-up of the ore is to burn away the sulphur (8) as sulphurous acid and to carry off the iron by means of fluxes in the form of scorite or slag.
