Chromatographic separation and determination of noble metals in matte-leach residues.
The practical application of various chromatographic methods to the analysis of residues obtained from the leaching of copper-nickel mattes is described. The procedure involves the separation of gold on a TBP-treated Porasil column, the separation of base metals by cation-exchange, the separation of tellurium from platinum-group metals, and the separation of the non-volatile platinum-group metals on one cellulose column.
