The extraction of copper from copper ore is done by reduction with carbon but the copper produced is not pure enough for use as a conductor so it is purefied using electrolysis Asked in Metal
Copper processing Copper processing Roasting smelting and 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
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes which will ultimately be made into products for everyday use The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
copper L SX EW operation the Bluebird plan of Ranchers Exploration and Development Corporation came on line1 Copper recovery by L SX EX in 1968 In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid The first process vat leaching of high grade copper oxide ore followed by EW of
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product Each process consists of several steps in which unwanted materials are physically or chemically removed and the concentration of copper is progressively increased
The results of the survey present a picture of the current water requirements of the copper industry The total water use figures are compared with the information obtained in the 1954 inventory of industrial water use by the Bureau of the Census Trends and
