of steel. Fifteen iron ore mines and fifteen ore concentration plants together withdrew annually about 89,000 million gallons to produce 15 million tons of iron ore concentrate, or 5,900 gallons per ton of concentrate. About 97 percent of the water used in the steel plants came from surface sources, 2.2 percent was
Lithium Mining | Processing Equipment | Flow Chart | Cases
Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite (LiAl (Si2O 5) 2, lepidolite K (Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2, spodumene LiAl (SiO 3) 2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.

Concentration of Ore
In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both physical and chemical means. The ore obtained after the completion of the ore concentration is called concentrate.
