Describe The Process Of Ores

Flash smelting. Flash smelting Finnish Liekkisulatus is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.

    The Bayer process involves four steps digestion clarification precipitation and calcination. In the first step bauxite is ground slurried with a solution of caustic soda sodium hydroxide and pumped into large pressure tanks called digesters where the ore is subjected to steam heat and pressure. The sodium hydroxide reacts with the aluminous minerals of bauxite to form a saturated solution of sodium

    May 22 2009 Ore A mineral from which metals can be extracted profitably is called a metal ore. Profitable extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal. So All Ores Are Minerals But All Minerals Are Not Ores. The most common metal ores are oxides and sulphides.

    Reduction of Metals Extraction from Ore ALevel Chemistry

    There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon reduction of the molten ore by electrolysis and reduction of the ore with a more reactive metal. Extraction using carbon. Metals such as zinc iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon .

    Concentration of Ores. An ore of a metal is an impure source this means other than the metal it consists of many other impurities such as sand grit clay rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores .

    Copper Mining and Extraction Sulfide Ores

    Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are See for further information on the leaching process.
