Hi there. The answer is refining. To obtain ultra pure metals and non-metals, they undergo refining, or the process of removing impurities. After mining or the extraction process, the final process in metallurgy is refining. Take not that this does not change the chemical composition of the metal being refined. The refining methods used depending on the physical and chemical properties of the metal are:
