Recovery of noble metals |
| abstract |
Case 6772(2) ABSTRACT OF THE DISCLOSURE A process for recovering Group VIII noble metals from tar is provided. The process involves heating a mixture of the Group VIII noble metal, tar and methyl iodide in a closed system at a temperature in excess of 50°C. During the process the Group VIII noble metal is precipitated in an insoluble form which can be separated by e.g. filtration. Precipitation preferably takes place at a temperature in the range 120 to 180°C. The process is particularly suitable for the recovery of either rhodium or iridium. |
