Patent ID: 7972412

Claim:
A method for recovering at least one platinum group metal (PGM) species as a corresponding PGM chloride salt in non-gaseous form from a feed product selected from the group consisting of chromite ore, chromite ore concentrate and PGM concentrate, said method comprising: (a) mixing the feed product with at least one chloride salt so as to produce a mixture, wherein the concentration of chloride salt in the mixture is suitable for converting at least one PGM species into a corresponding PGM chloride salt; (b) contacting the mixture with gaseous Cl 2 and CO at a temperature between about 240° C. and 800° C. to produce a catalytic system enabling a carbochlorination reaction to induce the conversion of said at least one PGM species into said corresponding PGM chloride salt while minimizing volatilization thereof; and (c) recovering said corresponding PGM chloride salt.
