Copper Mining and Production Processes Explained

    Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain ...

    Copper Ore Processing Methods

    The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

    Prior to the identification of copper as a micronutrient, it was regarded as a plant poison . Therefore, no discussion of copper toxicity can rightfully begin without mention of its use as a fungicide. In 1882, botanist Pierre-Marie-Alexis Millardet developed a copper-based formulation that saved the disease-ravaged French wine industry .
