Copper Mining and Production Processes Explained
Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
Eliminating Copper from Gold Ore
The gold is thus extracted together with some copper, and the metals are recovered by electrolytic precipitation, the gold, silver and copper falling to the bottom of the vats as a sludge. Zinc precipitation may also be used.

Copper Mining & Extraction Process Flow Chart
The copper oxide minimum minerals are dissolved by the acid to give a blue copper rich solution mainly of copper sulfate. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper. This process as the advantage of avoiding the smelting and refining stages required for sulfide ores.
Copper Leaching Method - Metallurgist & …
Where gold and silver are present in amounts sufficient to warrant their extraction, they are either converted into chlorides in the roasting furnace and afterward dissolved in brine, or other solvents, from which solutions they may be removed by any one of several well-known methods, or else they may be recovered from the residues in separate operations after the copper has been taken out by acid …
Processing, smelting and refining gold | World …
***copper remains in gold The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
Copper Mining and Processing: Processing of …
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 ...
Chapter 6 Copper Production Technology
Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have …

Valves for gold autoclave pressure oxidation …
Autoclave pressure oxidation (POX) is an effective pre-treatment option when extracting gold from refractory ore bodies, such as pyrite and arsenopyrite. While gold processing plants are the most common utilizers of POX technology, the process can also be applied to other metals, like copper, zinc and uranium. liming has a wide range of valves and services for POX process.
