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 ).

Foams in mineral flotation and separation processes

Ninety percent of the worlds copper, lead, zinc, molybdenum, antimony, and nickel are produced by processes employing concentration of ore by flota tion. Although the processing of mineral ores is by far the largest use of flotation separation, numerous other processes have been developed for the separation of other materials.

Copper extraction

Secondary sulfides those formed by supergene secondary enrichment are resistant (refractory) to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.
Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalc

Recovery of γFe2O3 from copper ore tailings by

The process of separation and recovery of γFe 2 O 3 is summarized in Figure 13. The pyrrhotite rich in copper ore tailings was oxidized to γFe 2 O 3 which was highly magnetic in magnetizing roasting. Meanwhile, sulfur in the form of SO 2 was released from the inside of pyrrhotite to the surface through slits.

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas.
