Gold Project Flowsheet Design | SRK Consulting
It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore.
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.
