W recovery from Searles Lake by ion exchange.
Tungsten News 1980 Summer; 18(3):3-4
An effective ion exchange operation to remove tungsten from Searles Lake brines using a pilot unit that has been operating since July 1979 at the Kerr-McGee Corp., Trona, California, is described. The extractive technique, developed by the Bureau of Mines, is based on a new tungsten-selective resin designated qrf. The objectives of the investigation includes, (1) proving the operational viability during seasonal changes in brine properties, (2) providing a tungsten-rich solution to enable completion of tungsten recovery research, and (3) supplying data for system escalation to enable recovering nearly 227,000 kg per year of tungstic oxide.
