Heavy growth: Rising demand from copper ore mining has supported industry revenue Revenue for the Copper, Silver, Lead and Zinc Smelting and Refining industry is expected to increase at an annualised % over the five years through 201819, to reach billion.
The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off
Gold and silver are byproducts of the copper mining and smelting process. They follow the same production pathway as the copper ore from the mine to the smelter. At the refinery, the copper anodes (which contain gold and silver) are lowered into an acid solution. Gold and silver drop off into the bottom of the tank as electrolytic slimes.
Feb 08, 2016· Opportunities. Vietnam presents major opportunities for the processing and refinery industry along with mining technologies and services. Canadian companies who consider entering the Vietnam mining market do so with a strategy of growing opportunities on .
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Codelco is in first place, and it''s followed by FreeportMcMoRan and Glencore. Read on to find out the rest of the top copperproducing companies. Copper prices rallied toward the end of 2016 ...

Prized for its ability to conduct heat and electricity, it is an element that helps facilitate the world as we know it, and is a focus of Vale''s investment.
Palladium is normally a platinum group Metal (PGM). It is a rare element and occurs along with deposits of platinum, nickel, copper, silver and gold and is therefore obtained as a byproduct of mining these metals PGM. The mining of palladium is a very intricate process because of the fact that palladium is so spread out under the surface and in the mines and requires using mechanical ...

These New World mines, much richer in silver, resulted in the rise of South and Central America as the largest silverproducing areas in the world. For the recovery of New World silver, the Patio process was employed. Silverbearing ore was ground and then mixed with salt, roasted copper ore, and mercury.
Most of the copper ore produced in Australia comes from underground mines. At a few Australian mines, copper is leached from a copper oxide ore to produce a copperrich solution that is then treated by solvent extraction and electrowinning to recover the copper metal.
"This technology allows a mine like this to continue to get a high enough grade to make it economic. By being able to process lower grade ore, we''re extending the life of the mine." There are many undeveloped copper mines throughout the world, particularly in North and South America as well as in Australia.
