This market is serviced by 4 large-scale calcium carbonate producers that account for around 30% of the market and an additional 20%–22% of the demand is met by imports. The remainder of the market is fragmented and is ered to by medium, small-scale, and unorganized producers.
Any calcium in the concentrated brine is removed as calcium carbonate by adding sodium carbonate. The brine that results from these chemical precipitations is then subjected to a carbonation process, where the lithium reacts with sodium carbonate at 80-90°C to produce technical-grade lithium carbonate.

Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
