    Copper Segregation Process

    May 07, 2020 · Reactions Involved. Segregation of copper from oxidized ore minerals probably involves a number of complex reactions. These include (1) the decomposition of sodium chloride, (2) the volatilization of copper chloride and (3) reduction of the copper chloride to metallic copper. The principal chemical reactions presumed to occur are as follows:

    Feb 22, 2019 · Both iron and copper can be extracted from the ore by heating with carbon. However, iron is a more reactive metal than copper. It is therefore a little harder to extract it from its ore. Which is added to a blast furnace to produce carbon monoxide and heat energy? The main chemical reaction producing the molten iron is: Fe2O3 + 3CO → 2Fe + 3CO.

    COPPER Copper production

    About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
