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 …

It was demonstrated that mining in Kabwe town in Zambia was responsible for heavy metal pollution. The spatial distribution of heavy metal concentrations extracted by 0.5 M nitric acid from soils around the closed Kabwe mine was successfully determined. The western side of the mine showed the highest concentrations of lead and zinc due …
