Lithium Carbonates/Bicarbonates TRIZ Cases
- Lithium Carbonate Recovery Using CO2 From Basic LiOH Solutions
CO2 precipitation recovers high-purity lithium carbonate from basic LiOH solutions while avoiding sodium contamination and high-sodium waste.
- Natural Brine Carbonation for Direct Lithium Carbonate Precipitation
Adjusting brine alkalinity enables direct lithium carbonate precipitation, avoiding evaporation ponds and separate carbonation facilities.
- Geothermal Brine Carbonation for Direct Lithium Carbonate Precipitation
Adjusting effective alkalinity enables direct lithium carbonate precipitation from geothermal brine without pre-concentration or transport.
- Lithium Carbonate Purification Through Thermal Precipitation and Hot Washing
This process combines pre-precipitation, thermal desorption, hot washing, and centrifugation to purify lithium carbonate.
- Lithium Carbonate Production via Thermal Reaction with Carbon
Heat-treating lithium sulfate and carbon material produces lithium carbonate powders in a controlled atmosphere.
- Selective Material Recovery from Natural Brines via CO2 Precipitation
Temperature-controlled CO2 injection precipitates impurities and target materials, cutting energy use and emissions versus evaporation ponds.
