| 摘要 |
hydrometallurgy. SUBSTANCE: when carrying out oxidized lead ore processing, sulfidizing is performed in crushing stage at 60 C using sodium polysulfide as sulfidizing agent. EFFECT: enabled involvement of difficult for concentration oxidized and mixed lead ores, increased proportion of lead sulfide in pulp before flotation and therefore increased yield of lead into concentrate. 1 tbl
