When recovering lithium carbonate, it can be extracted from a variety of materials. Here are a few of the main sources of materials:

Used Batteries:

Used batteries, especially lithium-ion batteries, are an important source of lithium carbonate for recycling. These batteries contain large amounts of metals and electrolytes, including lithium. Lithium can be extracted from used batteries through chemical dissolution and electrolysis, and then further through precipitation to obtain lithium carbonate.

Lithium carbonate production waste:

In the production process of lithium carbonate, some waste or by-products will be produced, which still contain a certain amount of lithium carbonate. The lithium carbonate in these wastes can be recovered by physical methods (such as evaporation, filtration, etc.) or chemical methods (such as adding appropriate chemical reagents for separation).

Industrial waste:

Certain industrial processes may produce wastes containing lithium carbonate, such as production wastes from ceramics, glass and other industries. The lithium carbonate in these wastes can be extracted through the corresponding recovery process.

Lithium-containing brines:

Although the salt lake brine itself is not a recycled material, it is one of the important raw material sources of lithium carbonate. Salt lake brine is rich in lithium resources, and the lithium in it can be separated through evaporation, concentration, precipitation and other steps, and then further processed into lithium carbonate. However, in the development process of salt lake brine resources, some waste materials containing lithium carbonate will also be generated, and these waste materials also have recycling value. Lithium brine acquisition quality standard data: 1, electrolyte: LiCl ≥ 99.5%; 2, moisture: ≤ 0.2%; 3, PH value: 3.0-4.0; 4, precipitate: ≤ 0.1%
