| Description |
The present study relates to the dissolution of tungsten bearing sludge by oxidative roasting followed by hydro-chloric acid (HCl)leaching and ammonia leaching. The process comprises roasting of tungsten containing powdered sludge in a oxygen atmosphere for converting tungsten oxide and other impurities in oxide form, leaching of roasted product with ammoniu, and leaching of the roasted product with hydrochloric acid and water. The process is easy to be carried out and could be applied in any exis-ting plant without requiring any additional equipment. More studies in detail are to be recommended.
