  • Separating Metals from Mud Mining Technologies

    2011-3-27 · Jan Pretty much all the base metals; copper, lead, zinc primarily. Many of the other metals are associated with the base metals, so platinum comes up as a nickel-copper type deposit, silver often comes with lead, and in all the major gold mines in the world now, the gold is actually a by-product of the copper production.Methods Used To Separate Copper Ore From Other,Copper Mining From Ore To Copper. About 80 of all copper extracted comes from sulphide ores. A typical ore contains only 0.5 to 2.0 copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock called gangue. The most common copper. Get Price
