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.

Claims (11)

1 . 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.

2 . 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.

3 . The treated brine of claim 2 , wherein the concentration of iron is greater than 0 mg/kg and less than 200 mg/kg.

4 . The treated brine of claim 2 , wherein the concentration of iron is greater than 0 mg/kg and less than 100 mg/kg.

5 . The treated brine of claim 2 , wherein the concentration of lithium ranges from greater than 1 mg/kg to less than 200 mg/kg.

6 . The treated brine of claim 2 , wherein the concentration of silica is greater than 0 mg/kg and less than 20 mg/kg, and the concentration of iron is greater than 0 mg/kg and less than 100 mg/kg.

7 . The treated brine of claim 2 , wherein the concentration of silica is greater than 0 mg/kg and less than 10 mg/kg, and the concentration of iron is greater than 0 mg/kg and less than 100 mg/kg.

8 . The treated brine of claim 2 , further comprising a concentration of sodium ranging from 40,000 to 80,000 mg/kg, a concentration of calcium ranging from 30,000 to 46,000 mg/kg, and a concentration of potassium ranging from 10,000 to 26,000 mg/kg.

9 . The treated brine of claim 2 , wherein the treated brine is a treated Salton Sea geothermal brine.

10 . A method of using a treated brine, the method comprising extracting one or more minerals from the composition of claim 2 .

11 . A method of using a treated brine, the method comprising a step of injecting the composition of claim 2 into a geothermal reservoir.
