Abstract
This invention relates to treated geothermal brine compositions containing reduced concentrations of iron, silica, and manganese compared to the untreated brines. Exemplary compositions contain a concentration of manganese 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, and the treated geothermal brine is derived from a Salton Sea geothermal reservoir.

An aqueous treated geothermal brine composition, the composition comprising dissolved manganese, dissolved silica, and dissolved iron, wherein the dissolved manganese has a concentration greater than zero and no more than 200 mg/kg, the dissolved silica has a concentration of 0 mg/kg to 80 mg/kg, and the dissolved iron has a concentration of 0 mg/kg to 300 mg/kg.
A treated geothermal brine composition comprising dissolved manganese, dissolved silica, and dissolved iron, wherein the dissolved manganese has a concentration greater than zero and no more than 100 mg/kg, the dissolved silica has a concentration of 0 mg/kg to 30 mg/kg, and the dissolved iron has a concentration of 0 mg/kg to 300 mg/kg, and wherein the treated geothermal brine is a treated Salton Sea geothermal brine.
A method of using an aqueous treated geothermal brine composition, the method comprising:
- providing an aqueous treated geothermal brine comprising a concentration of dissolved manganese greater than zero and no more than 200 mg/kg, a concentration of dissolved silica of 0 mg/kg to 80 mg/kg, and a concentration of dissolved iron of 0 mg/kg to 300 mg/kg;
- and
- at least one of:
- (i) providing the aqueous treated geothermal brine composition to a process for mineral extraction or (ii) injecting the aqueous treated geothermal brine composition into a geothermal reservoir.
