How copper is made
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. Some of these steps are conducted at the mine site itself, while others may be conducted at separate ...

An associated process is biooxidation. This is the oxidation of sulfide minerals associated with but not necessarily part of the mineral of interest to be extracted. Bioleaching is used today in commercial operations to process ores of copper, nickel, cobalt, zinc and uranium, whereas, biooxidation is used in gold processing and coal ...

The processing technology uses onestage grinding, preferential flotation process. The gold and copper concentrate product can be recovered once. In general, the gold recovery method of gold tailings is mainly the allslime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity ...

THE PRIMARY PRODUCTION OF PLATINUM GROUP METALS (PGMs)
On the surface the ore is crushed and milled into fine particles. Wet chemical treatment known as froth flotation produces a concentrate which is dried and smelted in an electric furnace at temperatures over 1,500°C. A matte containing the valuable metals is transferred to converters to remove iron and sulphur. PGMs are then separated from the ...

Mining and Refining – Process
Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting. Beneficiating ore also reduces the amount of material that needs to be transported and processed at the refinery. However, the benefits of ...

Some Experiments in Prehistoric Copper Smelting
It is demonstrated that workable metallic copper can be produced by a simple twostage process from chalcopyrite ore. This simpler process could have been in use before the more complied multistage matte smelting process described in the historical documents on early technology. The simpler process would probably have been operable by any society in prehistory which possessed twotiered ...

SXEW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SXEW reactor, the first process to take place is solvent extraction, which involves

copper processing | Definition, History, Facts | Britannica
copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products.. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a facecentred cubic crystal structure, and there is no critical temperature at which this crystal structure changes.
