Lithium
Lithium. Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite LiAl(Si 2 O 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.

the possibility for the recovery and exploitation of ne particles, but the recovery and utilization rate of conventional cyclone separation is seriously low, and the performance urgently should be optimized. In the present study, a new type of volute feed was proposed to strengthen the classication and recovery process of ne mineral particles.
Highly fractionated granites and rare-metal mineralization
They concluded that Li, Be, B, Rb and Cs may have been partially dissolved and remobilized from primary spodumene, muscovite and CGM into late-stage hydrothermal fluids, from which the secondary muscovite and Nb-rich CGM crystallized, revealing a progressive magmatic-hydrothermal process related to the rare-metal mineralization.
Lithium
The process of forming a lithium brine deposit begins with the weathering and erosion of rocks and minerals that contain lithium. Over time, lithium is released from these materials and carried by groundwater into underground aquifers or porous rock formations.
Deep Vector Exploration via Alteration Footprints and
The Weilasituo Li–Sn polymetallic deposits exhibit spatial and genetic relationships with magmatic–hydrothermal alteration, resulting in distinguishable mineral zonation patterns across the different metallic orebodies. The mineral zonation of breccia, quartz vein, and quartz porphyry orebodies are distinguished efficiently by regularly …
