Lime-Gypsum Processing of McDermitt Clay for Lithium Recovery

摘要

As part of its efforts to devise new and improved methods for recovering lithium from unconventional resources, the Bureau of Mines investigated a lime-gypsum-roast, water-leach technique for processing lithium-enriched (0.01-0.68 pct Li) clays. This report presents the results of a study of the technical feasibility of extracting lithium from raw material representative of clay beds associated with the McDermitt Caldera complex in Nevada and Oregon.
