Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or fluidized …
The first step in the copper manufacturing process is refining. Copper ore that is mined from the earth is typically mixed with other minerals, such as iron, sulfur, and silica. This mixture is then heated in a furnace to a temperature of 2,000 degrees Fahrenheit. This process removes most of the impurities from the copper ore and leaves a ...
Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.

Where sea water is clean and unpolluted aluminium brass has been successfully used. However in plants requiring iron ions to restrict inlet end corrosion, both 90-10 and 66-30-2-2 alloys have become more common; 66-30-2-2 Cu-Ni is often used in large plants for the heat rejection section and 90-10 in smaller plants. Heat Recovery Section
The ISA PROCESS and its Contribution to Electrolytic Copper _____ _____ Fig 3: ISA PROCESS Tankhouse at Copper Refineries, Australia The Electrorefining Process Electrorefining of copper consists of electrolytically dissolving copper from impure anodes of about 99.7% copper, and selectively plating the dissolved copper in pure form onto the ...
Copper passes from the aqueous leach liquor phase to the organic phase in the extraction section and back from the organic to the aqueous electrowinning plant feed in the stripping section.
