Treated Geothermal Brine Compositions With Reduced Concentrations of Silica, Iron, and Zinc

Abstract

This invention relates to treated geothermal brine compositions containing reduced concentrations of iron, silica, and zinc compared to the untreated brines. Exemplary compositions contain concentration of zinc ranges from 0 to 300 mg/kg, concentration of silica ranges from 0 to 30 mg/kg, concentration of iron ranges from 0 to 300 mg/kg. Exemplary compositions also contain reduced concentrations of elements like lithium, manganese, arsenic, barium, and lead. Exemplary compositions include Salton Sea brines containing a concentration of zinc less than 10 mg/kg, a concentration of silica ranging from less than 10 mg/kg, and a concentration of iron less than 10 mg/kg.
