P-CAC, A Unique Separation Technology for PGM Recovery

Preparative Continuous Annular Chromatography, or P-CAC, is an innovative separation technology, a unique approach to high-performance chromatography for the separation of PGM component mixtures from solutions. P-CAC consists of inlet/distribution head and outer/inner cylinders, and bottom plate/fraction-collection as well. P-CAC has been applied in biotechnological and pharmaceutical downstream processing. This was the first time to explore an efficient PGM separation and recovery at the Copper Refinery. Laboratory trials with using a chloride solution for raffination for PGM are described and the tests results are presented in this paper.
