Abstract
This invention relates to treated geothermal brine compositions containing reduced concentrations of iron and silica compared to the untreated brines. Exemplary compositions of the treated brine contain concentration of silica ranging from 0 to 80 mg/kg and concentration of iron ranging from 0 to 300 mg/kg. Exemplary compositions of the reduced silica and iron brines also contain reduced concentrations of elements like arsenic, barium, lead, and lithium.
