| titleOfInvention | ARSENO-AURIFE PIRITES DEZARSENER TECHNOLOGY |
| abstract | The invention relates to a process for extracting arsenic from arsenic-golden pyrites. The process according to the invention consists in treating the pyrites having an arsenic content of at least 0.3% with a solution containing sodium sulfide and sodium hydroxide at a temperature of 40 ... 60 ° C for 2 ... 4 h , followed by filtration of the slurry from which the pyrite is separated, having an arsenic content of 0.2 ... 0.5%, and the resulting alkaline solution is acidified with sulfuric acid to a value of 0.5 ... 1, from which separates arsenic sulfide having a concentration of 98.5% and a grain size of 30 ... 70 μm. |
