Abstract
This invention relates to treated geothermal brine compositions containing reduced concentrations of lithium, iron and silica compared to the untreated brines. Exemplary compositions contain concentration of lithium ranges from 0 to 200 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 arsenic, barium, and lead.

A treated brine composition comprising a concentration of silica ranging from greater than 0 mg/kg to less than 80 mg/kg, a concentration of arsenic ranging from greater than 0 mg/kg to less than 7 mg/kg, a concentration of iron ranging from greater than 0 mg/kg to less than 300 mg/kg, and recoverable amounts of one or more metals selected from the group consisting of lithium, manganese, rubidium, cesium and zinc or mixtures thereof, the treated brine composition comprising a concentration of lithium ranging from greater than 0 mg/kg to less than 200 mg/kg.
A treated brine composition comprising lithium, silica, iron, boron, barium, and strontium, the treated brine composition comprising a concentration of silica ranging from greater than 0 mg/kg to less than 80 mg/kg, and a concentration of iron ranging from greater than 0 mg/kg to less than 300 mg/kg.
