Technology for complex processing of the leaded slimes, cakes, dusts

 

Short description:

 

The technology for processing of the leaded slimes, cakes, dusts with the selective separation of rhenium and osmium in single stage during the reduction smelting is developed. The proposed technology provides of:

  • polyselection of metals;
  • high degree of extraction of Os (97-99%) and Re (97-98%) in the melting products - lead alloy and sodium sulphate slag, respectively.

Method of extraction of osmium from the lead alloy with obtaining of the concentrate that containing 55-67% metallic osmium is developed.
