The salinity of the Great Salt Lake in UT is higher than that of seawater. It ranges from 1090 kg/m3 at a salinity of 118 g/L to 1145 kg/m3 at a salinity of 182 g/L. Li concentrations in the north arm of the Great Salt Lake are ~60 ppm. Assuming economic recovery of Li from brines is feasible at concentrations higher than 100 mg/L; what mass of water needs to be evaporated from each L of water from the north arm of the Great Salt Lake to make economic recovery feasible?
