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.

Claims (25)

1. A method of producing an aqueous treated brine composition derived from a brine source, the method comprising:

processing a brine in a silica removal process to reduce the concentration of silica and iron in the brine;

processing the brine in a lithium recovery process to extract lithium, wherein the lithium recovery process comprises:

providing the brine to a column;

contacting the brine with an extraction material in the column to adsorb lithium from the brine;

eluting the adsorbed lithium from the column with a solvent to produce the treated brine composition;

wherein the treated brine composition comprises 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 greater than zero and no more than 80 mg/kg, and the dissolved iron has a concentration greater than zero and no more than 300 mg/kg.

2. The method of claim 1 , wherein the concentration of the dissolved manganese is no more than 200 mg/kg, the concentration of the dissolved silica is no more than 30 mg/kg, and the concentration of the dissolved iron is no more than 300 mg/kg.

3. The method of claim 1 , wherein the concentration of the dissolved manganese is less than 100 mg/kg, the concentration of the dissolved silica is less than 30 mg/kg, and the concentration of the dissolved iron is less than 300 mg/kg.

4. The method of claim 1 , wherein the concentration of the dissolved manganese is less than 50 mg/kg, the concentration of the dissolved silica is less than 30 mg/kg, and the concentration of the dissolved iron is less than 300 mg/kg.

5. The method of claim 1 , wherein the concentration of the dissolved manganese is less than 20 mg/kg, the concentration of the dissolved silica is less than 20 mg/kg, and the concentration of the dissolved iron is less than 100 mg/kg.

6. The method of claim 1 , wherein the concentration of the dissolved manganese is less than 20 mg/kg, the concentration of the dissolved silica is less than 20 mg/kg, and the concentration of the dissolved iron is less than 50 mg/kg.

7. The method of claim 1 , wherein the concentration of the dissolved manganese is less than 10 mg/kg, the concentration of the dissolved silica is less than 10 mg/kg, and the concentration of the dissolved iron is less than 100 mg/kg.

8. The method of claim 1 , wherein the concentration of the dissolved manganese is less than 10 mg/kg, the concentration of the dissolved silica is less than 10 mg/kg, and the concentration of the dissolved iron is less than 10 mg/kg.

9. The method of claim 1 , wherein the concentration of the dissolved manganese is less than 5 mg/kg, the concentration of the dissolved silica is less than 5 mg/kg, and the concentration of the dissolved iron is less than 5 mg/kg.

10. The method of claim 1 , wherein the brine source is a geothermal brine, oilfield brine, smackover brine, hydrothermal brine, or Salton Sea brine.

11. The method of claim 1 , wherein the treated brine composition further comprises sodium in a concentration of at least 50,000 mg/kg and potassium in a concentration of at least 9,000 mg/kg.

12. The method of claim 1 , wherein the dissolved manganese has a concentration greater than zero and no more than 100 mg/kg, the dissolved silica has a concentration greater than zero and no more than 30 mg/kg, and the dissolved iron has a concentration greater than zero and no more than 300 mg/kg, and wherein the treated brine composition is a treated Salton Sea brine.

13. The method of claim 12 , wherein the concentration of the dissolved manganese is less than 20 mg/kg, the concentration of the dissolved silica is less than 20 mg/kg, and the concentration of the dissolved iron is less than 200 mg/kg.

14. A method of claim 1 further comprising using the aqueous treated brine composition, the method comprising at least one of:

(i) extracting minerals from the aqueous treated brine composition, or

(ii) injecting the aqueous treated brine composition into a reservoir.

15. The method of claim 14 , wherein the process for mineral extraction comprises extracting at least one of lithium, zinc, lead, potassium, rubidium, cesium, or a phosphate from the aqueous treated brine composition.

16. The method of claim 14 , wherein the brine source is a geothermal brine, oilfield brine, smackover brine, hydrothermal brine, or Salton Sea brine.

17. The method of claim 1 , wherein the treated brine composition recoverable amounts of one or more metals selected from the group consisting of lithium, manganese, lead, rubidium, and cesium or mixtures thereof.
