Abstract
Methods for extracting lithium from brines may include evaporating at least a portion of a brine using a number of one or more solar evaporation ponds to form a first slurry. A first solid may be separated from the first slurry and combined with an amount of a first precipitation additive to form a second slurry. A first liquid may be separated from the second slurry and at least a portion of the first liquid may be evaporated in a solar evaporation pond to form a third slurry. A second liquid may be separated from the third slurry and combined with an amount of a second precipitation additive to form a fourth slurry. A second solid may be separated from the fourth slurry and rehydrated, forming a fifth slurry. About 90 wt % or more of a salt in a solid product separated from the fifth slurry may be lithium carbonate.
