Metallurgy of Copper Copper Mining: The commonest Ore used in the extraction of copper is Chalcopyrite (CuFeS2) also known as Copper Pyrites and other such sulfides. 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 … Read more
Natural Resources are useful raw materials that we get from the Earth. They occur naturally, which means that humans cannot make Natural Resources. Instead, we use and modify natural resources in ways that are beneficial to us. The materials used in human-made objects are natural resources.
