Copper is one of Construction Waste Crusher earliest metals that be found and used by human beings, it is aubergine, with the specific gravity of 8.89, and melting point of 1083.4℃. Copper and its alloy are widely used because of its good electric conductivity and heat conductivity, strong resistance to corrosion, easy processing, favorable tensile strength and fatigue resistance. It ranks only second to steel and aluminum in metal material consumption, and become the obbligato base material and strategic supplies of national economy, people's livelihood, defense engineering and even advanced technology. It has widely applications in the industries of electric, machinery, chemical, defense engineering, and etc. copper concentrate is the concentrate that processed by the low grade copper contained raw ore, it can be used to smelt copper directly.
At present, the raw materials to refine copper in China mainly are towanite, chalcocite, bornite, malachite and etc. According to the technical conditions of smelting, the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide, that is, sulfide ore, which contains less than 10% copper oxide；oxidized ore, which contains more than 30% copper oxide; mixed ore, which contains 10%~30% copper oxide.
