Abstract
Modern waterbodies technologies protecting from pollution are based, mostly, on methods of removing elements from contaminated water that are dangerous for people. As a result, this process accumulates wastes that must be recovered by rather expensive ways. At the same time, there are metals that have market demand. These include copper that is in good supply in Karabash industrial area’s wastewaters in South Ural in the Russian Federation. The article analyzes the efficiency of selective copper removing by two most widely used methods in the mining industry: cementation on iron and extraction. There are data that characterize the efficiency of selective copper recovery, obtained with the help of laboratory studies. The obtained results indicate that both methods for the efficiency of copper extraction from contaminated wastewater are the same. However, the extraction method gives a more pure final product - copper concentrate, besides a large amount of iron appears in water after cementation, which requires further purification of water from contamination.
