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.

di erent equipment types have attributes that can interact in a complex way with respect to productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the pit.
· In this method, ore is mined in horizontal slices, starting from the bottom to the top of the stope. The broken ore is left in the mined-out stope and serves as a support to the stope walls and a working platform for mining the ore above. Shrinkage stoping has a high recovery but requires steep and narrow ore bodies.
