Recovering Vanadium from Dolomitic Nevada Shale.

PB234692

Publication Date	1974
Personal Author	Brooks, P. T.; Potter, G. M.
Page Count	26
Abstract	A process for extracting 69 percent of the vanadium from weathered Nevada dolomitic shale was developed on a laboratory scale as a result of a Bureau of Mines study to develop new vanadium resources. The process essentially is comprised of salt roasting, leaching with dilute sulfuric acid, solvent extraction, and precipitation of vanadium as ammonium metavanadate. A preliminary cost appraisal for processing 1,500 tons per day of dry, weathered shale indicated a 46 percent return on investment before taxes. Less favorable results were achieved using more difficult to treat, carbonaceous, unweathered shale.
