Concentration of Ores: Hydraulic Washing, Froth Flotation with
Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of minerals and gangue.

How is Iron Extracted from Iron Ore
C + O2 → CO2. The heat produced by this reaction is the main source of heat in the blast furnace that is used for iron production. At the bottom of the furnace, the temperature is very high, which causes more of the coke to react with carbon dioxide, producing carbon monoxide. C + CO2 → 2CO. The carbon monoxide then becomes the "reducing
