| titleOfInvention | Method for hydrometallurgic processing lead-containing concentrates |
| abstract | FIELD: non-ferrous metal metallurgy. n SUBSTANCE: invention can be used for hydrometallurgic processing lead and lead-zinc ores and concentrates. Method involves leaching sulfide lead-containing concentrates in ferric (III) nitrate solutions that is carried out in the mole ratio Pb : Fe (III) = 1:2, at temperature 15-25 C for 15-20 min using lead concentrate with particles size less 0.1 mm. The ferric (III) nitrate solution is prepared by dissolving ferric oxide in nitric acid prepared in the step of treatment of lead nitrated solution from iron ions, and fed to the second stage in leaching. Method provides enhancing extraction of lead, excludes ecologically danger processes, reduces consumptions for producing metallic lead and its salts. n EFFECT: improved processing method. n 2 cl, 6 tbl, 6 ex |
