Copper concentrate generally contains 25 percent to 30 percent copper. It is the resulting product after mine ore (containing less than 1 percent copper) has been crushed, milled and concentrated Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper. On the other hand, copper concentrate is a more refined form of copper ore. It is the result of further processing, where impurities are removed, and the copper content is concentrated, typically through processes like flotation or smelting.  Copper concentrates are made up of primary and/or secondary copper sulfide minerals, containing small amounts of impurities. The variability of the mineral content and composition depends mainly on the geographical location and age of the mine site
