tungsten extraction wolframite

USA Process for recovering high purity tungsten The method of extracting tungsten from wolframite concentrates

A process for recovering tungsten values in the form of ammonium paratungstate from tungsten ores and ore concentrates particularly wolframite ores and ore concentrates incorporating a plurality of steps for necessary removal of impurities and formation of the product ammonium paratungstate The steps of the process include grinding caustic leaching filtrations chemical treatment Dissolution wolframite concentrate lead in glass thermostatted vessel stirring is carried out using a magnetic stirrer for 3 4 hours tungsten acid is almost completely in solution The resulting solution is separated from nerastvorimogo residue by filtration or by centrifugation and analyzed for the content of tungsten photometric method
