methods of extraction iron ore

Iron ore Wikipedia

The Lowergrade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easilyGold extraction Wikipedia,Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold2. Extraction of Iron and Steelmaking Doc Brown,How do we extract iron from its mineral ores How do we convert it into steel The materials needed i.e. limestone, coke, air and iron ore and the chemistry of the blast furnace are fully described. Why convert iron into steel How do you make steel The manufacture of steel alloys is further described. Scroll down for revision notes on extraction
