| titleOfInvention | Method of copper electrorefining leaded slimes treatment (versions) |
| abstract | FIELD: metallurgy. n SUBSTANCE: invention relates to copper electrorefining leaded slimes treatment, with slimes containing lead, antimony, aurum, silver and rare chalcogens and may be used to produce collective concentrates of precious metals. The method considers two versions of slimes treatment. Both versions include consecutive leaching of slimes and floatation. According to the first version, slime is leached in sulfuric acid solution at a temperature of 104-106°C, partial oxygen pressure of 0.02-0.1 MPa and stirring with oxygen absorption speed no less than 0.001 mole O 2 /m 3 -hour-Pa, filtered and floated. According to the second version, slime is subjected to liquid-phase sulfurisation at a temperature 160-200°C, then to leaching by ferric (II) sulfate, filtration and floatation. Extraction of aurum and silver in concentrate reached 99.8%. n EFFECT: slime is reduced and content of precious metals therein increases 3,6-4,8 times. n 2 cl, 2 ex, 4 dwg, 1 tbl |
