| titleOfInvention | A kind of method and filter press device for extracting tungsten and cobalt from tungsten-containing cobalt waste |
| abstract | A method for extracting tungsten and cobalt from tungsten-containing cobalt waste and a filter press device, wherein the method comprises the following steps: S1: cooking the tungsten-containing cobalt waste to produce a sodium tungstate solution; S2: performing two steps on the sodium tungstate solution The second pressure filtration to obtain a high-purity sodium tungstate solution and output; S3: the filter residue after the pressure filtration in S2 is washed, and the washed filtrate is subjected to re-pressure filtration and output, so as to realize the recovery of tungsten; S4: the S3: The filter residue after medium pressure filtration is collected and then digested with acid to obtain a cobalt liquid; S5: The cobalt liquid is subjected to two pressure filtrations to obtain a pure cobalt liquid; S6: The pure cobalt liquid is reprocessed to obtain a high-purity cobalt liquid. The present invention also includes a filter press device. The invention has high working efficiency, high recovery rate of tungsten and cobalt, and no pollution occurs in the recovery process. |
