| titleOfInvention | A method for recovery and harmlessness of beryllium in beryllium-containing sludge |
| abstract | The invention provides a method for recovering and harmless beryllium in beryllium-containing sludge, comprising steps: S1, adding beryllium-containing sludge with a particle size of 200-600 mesh and a mineralizer into a hydrothermal reactor for hydrothermal treatment, After the hydrothermal reactor is cooled to room temperature, the mixture in the hydrothermal reactor is separated from the solid and liquid to obtain the beryllium-containing filtrate; S2, the beryllium-containing filtrate is mixed with the saponification extractant, and the organic phase is obtained after standing, and the saponification extractant is the extractant A mixed solution with the first lye; S3, mixing the S2 organic phase with a stripping agent and standing still to obtain an aqueous phase, the aqueous phase is a stripping solution containing beryllium; the stripping agent is a mixed solution of sodium carbonate and ammonium fluoride; S4, heating and hydrolyzing the beryllium-containing back-extraction solution to obtain a final product. The invention realizes beryllium recovery and harmless treatment of beryllium-containing sludge, has few extraction stages and high beryllium recovery rate. |
