  • Tungsten processingBritannica

    Tungsten ores frequently occur in association with sulfides and arsenides, which can be removed by roasting in air for two to four hours at 800° C 1,450° F. In order to produce ammonium paratungstate APT, an intermediate compound in production of the pure metal, ores may be decomposed by acid leaching or by the autoclavesoda process.
