Abstract
As part of its program for developing plentiful domestic resources, the Bureau of Mines, U.S. Department of the Interior, is investigating methods for recovering metal values from geobrines. Two precipitation techniques were evaluated for recovering selected metal values from Salton Sea KGRA brines. Lime addition precipitates more tan 95 pct of the iron, manganese, lead, and zinc while sulfide addition precipitates more than 90 pct of the lead and zinc and lesser amounts of iron and manganese. A comparison of these techniques and a discussion of the respective advantages and disadvantages are presented.
