Commercial Lithium Production and Mining of Lithium - ThoughtCo
By. Terence Bell. Updated on August 21, 2020. Most lithium is commercially produced from either the extraction of lithium-containing salts from underground brine reservoirs or the mining of lithium-containing rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until 2022.

CHAPTER 1 MINERAL DRESSING - Webs
The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.

The Reading Rare Earth Magnetic Drum (RED) uses a unique 5 pole magnetic element to generate a field intensity in excess of 0.7 Tesla on the drum skin. The magnetic element design affords the maximum field gradient and the 5 poles enables additional cleaning of the magnetic stream. This gives a very selective separation at high throughputs compared to alternative magnetic separators.
