| 发明名称 | Precious metal recovery | ||
| 摘要 | A process for treating an off-gas from the thermal processing of a precious-metal-containing feedstock, the process comprising cooling the off-gas to a temperature of from 300 to 500° C.; passing the cooled off-gas through a first particulate filter to recover particulate material; and dosing the off-gas from the first particulate filter with a sorbent material and passing the dosed off-gas through a second particulate filter; wherein at least a portion of the particulate material recovered from the first particulate filter is recycled into the thermal processing of the precious-metal-containing feedstock. | ||
