Abstract
The U.S. Department of the Interior, Bureau of Mines, devised methods for recovering metal values from postflash geothermal brines. A zns-pbs concentrate was obtained by treating brine with h2s and lime. Subsequently iron and maganese were removed by using a lime slurry to adjust the ph of the brine to 8.5. Lithium was precipitated by treating brine with a solution of alcl3 and adjusting the ph to 7.5 With a lime slurry. The mixed al-li precipitate was dissolved with hcl, and the resulting solution was treated with gaseous hcl to separate li from al and recover alcl3 for recycle. The licl solution was distilled to recover hcl, and the distillation residue was purified to remove cacl2. The licl product was 99.9 pct pure. The treated brine was acidified to ph 5.5 and returned to the injection well.
