Copper: smelting and classifiion; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

Copper and silver are indispensable natural resources for the development of global economy. During 60 years of company's activity, KGHM has extracted over a billion tonne of mining output and has produced 20 million tonnes of copper. Current deposits will suffice for the next 4050 years of mining activities. The copper ore deposit operated by KGHM in Poland dips monoclinally

 ·  · About 80% of global copper mine production comes sulphide ores that ore processed using grinding and flotation plants to produce concentrates for smelting. The rest comes from mines using dump or heap leaching, solvent extraction and electrowinning to produce hode copper. Most copper mines are large, low grade, open pits.

 · With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the increased amounts of secondary products .

Production. Gold and silver are products of the copper mining and smelting process. They follow the same production pathway as our copper ore from the mine to the smelter. At the refinery, we lower copper anodes (which contain gold and silver) into an acid solution. Gold and silver drop off into the bottom of the tank as electrolytic slimes.

Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of highgrade copper ore around Lake Superior began. The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States.
