Lithium Mining
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.

Mining Methods: Block Caving
Mar 15, 2017Most underground mining methods have prohibitively high operating costs, which only allow high grade deposits to be mined. Block caving has a high production rate, which means high capital costs at the start of the project but relatively low operating costs. If there is enough ore, initial capital will be recouped over the life of the deposit.

Barite. Barite is a mineral composed of barium sulfate (BaSO4). It receives its name from the Greek word barys which means heavy. This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical
