Stage two of copper extraction

This stage is typically what we envision when we think of mining. Some exploration and development may continue at this stage, as well. The extraction stage can take from 5-30 years to complete, although many mines have been open for more than 100 years, and may cost anywhere from a few million dollars to hundreds of millions of dollars a year

    Primary copper production starts with the extraction of copper-bearing ores. There are two basic ways of copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or open-pit mining, is the predominant mining method for copper in the world. After mining, copper is

    There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide: In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: Suppose the yield of the first step is 78.% and the yield of the second step is 84.%

    Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of
