Abstract
A process for extracting 69 percent of the vanadium from weathered Nevada dolomitic shale containing about 1 percent v2o5 was developed on a laboratory scale by the Bureau of Mines. The process essentially consists of salt roasting, leaching with dilute sulfuric acid, solvent extraction, and precipitation of vanadium as ammonium metavanadate. Carbonaceous unweathered shale was less amenable to treatment. A preliminary cost estimate for mining and processing 1,500 tons per day of weathered shale indicated a production cost of about $1 per pound of v2o5. Considering recent sales at nearly $1.75 Per pound of contained v2o5, larger scale testing to obtain more definitive process design and evaluation data may be warranted.
