Purification of copper powders produced by cementation from the cementing metal

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

A copper powder produced by cementing copper with iron from a sulfate solution can be purified from iron by treatment with a sulfuric acid solution. Reverse dissolution of copper in this process can be reduced by employing a protective atmosphere generated by the addition of sodium carbonate to the H2SO4, solution. A necessary condition for the effective purification of finely divided copper from the cementing metal is deposition of copper in loose form.
