Comparison and review of modern and environmentally friendly methods of extracting copper from ore

Environmental effects of exploration and extraction of mineral Resources as an integral part of today's mining project are developed. In a new mineral economic activities of exploration and extraction while have an economic justification that are not be dangerous for existence of a human. Thus correct understanding regarding environmental dimension of the problem cause economic activity to be guide by thoughtful. The environmental impact of mining in concept of rock movement and mineral ingredients to achieve the mineral substance are dedicated the most important part of environmental pollution of mining. Disorganization and displaced land especially open mines will remain like an enteral legacy on earth until combined with the surface process that lead to reaction, the most important product of this reaction is pollution. Abundant of copper element in nature and focus on sulfide ore is due to oxidation of sulfide minerals in the presence of weather, water and bacteria phenomenon occur that we call acid mine. This phenomenon is considered as the most important and most common problem of environmental pollution of the world sulfide mining. The use of biotechnology and bio leaching of copper extraction especially copper production from low grade mine of copper instead of common methods not only reduce the environmental implication of copper production it will also increase production, reduce production time, reduce operational costs and investment in extraction. In this paper according to the subjects were told regarding investigation new method and environmentally friendly extraction of copper from concentrate and comparison common methods of melting will be discussed.
