Extractive Metallurgy of Copper. ... The slime, in particular, contains significant levels of gold, silver, selenium, and tellurium. The recovery of these metals has a significant impact on the profitability of copper production facilities. Select Chapter 22 Costs of Copper Production.
discovered that heat made copper more malleable. Casting and smelting of copper began around (see figure 62). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their intermetallic compounds, and their mixtures, which are called encompasses both the science and the technology of metals. That is, the way in which science is applied to the production of metals, and the engineering of metal components used ...

May 25, 2020· Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into purer form. The field of extractive metallurgy encompasses many specialty subdisciplines, including mineral processing, hydrometallurgy, pyrometallurgy, and electrometallurgy.
Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. The cathode plates are coated with graphite in order to remove depositing copper. The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity.

steadily. Cobalt is produced mostly as a byproduct of other major metal extraction processes – mainly copper and nickel – and in recent decades the nickel industry has been the major source of cobalt. Now however the Democratic Republic of Congo (DRC) coppercobalt production is coming to the fore once again after a 20year period of decline.

The coppermaking process illustrates well this point. In some cases copper extraction can be divided into three steps: (i) roasting (which can be optional for some coppermaking routes); (ii) matte smelting (reverberatory, electric, or flash smelting furnaces); (iii) converting (conversion of matte to blister copper).
