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 geothermal brine composition, the composition comprising a treated geothermal brine comprising lithium, silica, iron, and lead, and having a concentration of lithium of no more than 200 mg/kg, a concentration of silica of no more than 80 mg/kg, a concentration of iron of no more than 300 mg/kg, and a concentration of lead greater than 25 mg/kg, wherein the treated geothermal brine comprises recoverable amounts of one or more of metals selected from the group consisting of boron, cesium, and rubidium.
A treated geothermal brine composition, the composition comprising a treated geothermal brine comprising lithium, silica, iron, and lead, and having a concentration of lithium less than 200 mg/kg, a concentration of silica less than 30 mg/kg, a concentration of iron less more than 100 mg/kg, and a concentration of lead greater than 25 mg/kg, wherein said geothermal brine is a Salton Sea brine.
A treated geothermal brine composition, the composition comprising a treated geothermal brine comprising lithium, silica, iron, lead, and zinc, and having a concentration of lithium no more than 200 mg/kg, a concentration of silica no more than 80 mg/kg, a concentration of iron no more than 300 mg/kg, a concentration of lead greater than 25 mg/kg, and a concentration of zinc greater than 300 mg/kg.
