A closed-loop process to recover lithium carbonate from cathode scrap of lithium-ion battery (LIB) is developed. Lithium could be selectively leached into solution using formic acid while aluminum remained as the metallic form, and most of the other metals from the cathode scrap could be precipitated out. This phenomenon clearly demonstrates that formic acid can be used for lithium recovery ...

Sodium carbonate (Na2CO3) or Soda ash Sodium carbonate is a powerful basic flux that reacts with silica-based (acidic) minerals to form a fusible sodium silicate. Na2CO3 + SiO2 = Na2SiO3 + CO2. There can be problems with soda ash reactions. The CO2 gas that is produced can cause frothing if the temperature is too high.
