| titleOfInvention | A kind of extracting method of arsenical pyrite |
| abstract | The invention belongs to technical field of wet metallurgy, more particularly to a kind of extracting method of arsenical pyrite.First, arsenical pyrite is crushed, and add in salpeter solution, sodium nitrite and peroxide and be ultrasonically treated, hydrochloric acid and calcium hypochlorite are subsequently added into, is ultrasonically treated again, it filters and leaches acquisition with basic anionic resin solution containing golden filtrate, it filters again and adds in thiourea solution parsing, add reducing agent reduction treatment, be then filtered, the filter residue of acquisition is dried to get bronze.Pass through the stringent control of technological parameter in each step so that Au plasma rate reaches more than 97.9%. |
