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.

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

One way to reduce calcium carbonate formation is to reduce carbon dioxide input by sparging pure oxygen rather than air into the cyanidation process, although at significant cost. An alternative is to use lime in a CO 2 scrubbing system, Reaction (8), ( Samari et al., 2020 ) prior to sparging the scrubbed air into the cyanidation reactor.
