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.
