    Copper Mining and Processing Processing of Copper Ores. Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes which will ultimately be made into products for everyday use.The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and

    The finely crushed ore is concentrated by Froth-Floatation process. The finely crushed ore is suspended in water containing a little amount of pine oil. A blast of air is passed through the suspension. The particles get wetted by the oil and float as a froth which is skimmed. The gangue sinks to the bottom

    Jan 26, 2021 Copper sulphide ore deposits are of great economic significance for copper extraction. In order to enrich copper sulphides, froth flotation at alkaline pH is typically applied to reject associated gangue minerals, in particular pyrite before the subsequent pyrometallurgical treatment to extract copper from copper sulphides [].The selective separation in flotation is driven by a difference in
