  • Copper Ore Processing Methods

    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 directsmelting ores are produced, the bulk of the copper oreCopper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides The percentage of copper in the actual ore is too low for direct extraction of copper to be viable The concentration of ore is required and it is done by the Froth Flotation method ConcentrationExtraction Of Copper | Mining, Concentration, Smelting

  • Spectrophotometric Determination of Copper

    Branicoda Copper Mine is considering opening up a new mining site The geologists feel that there might be a lot of copper at this new site Samples of ores taken from the new site were sent to Water Wagon Laboratories to be tested The ore samples were recently added to a sulfuric acid solution to bring out the Cu2+ (copper(II) ions) intoPreconcentration stages are generally employed to process base and precious metals where the feed grades are inferior The preconcentration could remove major gangue minerals and enrich the desired metal content Further, it improves the efficiency of subsequent concentration stages In the present investigation, preconcentration studies were carried out on the mixed copper ore fromAn Investigation into Preconcentration of LowGrade

  • Answered: Which method of concentration of an ore |

    Which method of concentration of an ore is preferred in the following cases and why? (1) The ore has higher density particles mixed with a large bulk of low density impurities (2) The ore consists of copper sulphide intermixed with clay particles Give an example of amalgam checkcircleCopper ore is mainly copper sulfide or copperoxide ore Flotation methods were applied to copper sulfide ore to recover a refined copper ore Copper can be obtained after the smelting process Flotation is now one of the main methods for dealing with copperoxide ore In addition, hydrometallurgy has also been widely adoptedTechniques of copper recovery from Mexican copper oxide
