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 …
lithium. Among the pegmatite minerals, only spodu- mene and petaline are known to occur in deposits large enough to support large tonnage operations. Spodumene, a lithium-aluminum-silicate, is the principal lithium mineral mined in the U. S. Lithium Corp. of America, during its rapid de- velopment and growth, has successfully employed
Ore beneficiation processes such as froth flotation can be used to upgrade sediments to produce concentrates between 4% and 8% Li 2 O. Mineral concentrates (such as spodumene) typically need to be ...
Extracting lithium from ores has higher operating costs than conventional extraction from brine, however, the theory of supply and demand makes the processing economically prudent because of the increasing price of lithium.
