Abstract

Sodium and potassium sulphides and thiosulphates are formed by heating finely-divided copper sulphide with solid caustic soda or potash, or with a strong solution of caustic soda, or with a mixture of caustic soda or potash and sodium carbonate, common salt, sodium sulphate, sodium sulphide, or lime, and with or without the addition of a small proportion of powdered coal. The operation may be carried out in an atmosphere of hydrogen or gases containing hydrogen. Reference has been directed by the Comptroller to Specification 624/71.
