Concentration of Ores: Hydraulic Washing, Froth Flotation
Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores or even dressing or benefaction. Now there are numerous ways to carry out the concentration of ores. The correct method is chosen based on the physical and chemical properties of the metal.
Copper Mining and Processing: Processing of Copper Ores
Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are higher,
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated
However, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first. Initial concentration techniques included handsorting and gravity concentration. They resulted in high losses of copper.
What is Concentration of Ore? definition and methods
The concentration of Ore is a method of eliminating gangue particles or other impurities. Oredressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step.
This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particles. Generally metal ores are heavier than the gangue associated with them. By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind.
