| titleOfInvention | METHOD FOR SEPARATING PURE ARSENSULFIDE FROM BALLASTIC BACKPACKS |
| abstract | The invention relates to a process for the treatment of arsenic sulfide-containing residues, as obtained in the denaturation of phosphoric acid, by separation of the valuable substance "arsenic sulfide" contained therein. The aim of the invention is to propose an environmentally friendly and economically favorable process for the separation of pure arsenic sulfide from arsenic sulfide-containing residues. This is achieved according to the invention by the arsenic sulphide being brought to a product which can be filtered off as a pure product by basic leaching in a 1st stage and heating at room temperature in a 2nd stage, which makes it possible to use it as valuable product. {Arsulphide-containing residues; Method; refurbishment; Separation; Arsenic sulfide-pure product; basic leaching; acidification; Warmth; filterable form; environmentally friendly} |
