20160060727 | PRECIOUS METAL RECOVERY - 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. | 03-03-2016 |
20140318312 | BASE METAL RECOVERY - The present invention relates to a method for the treatment of metal-containing waste, the method comprising: (i) introducing a particulate metal-containing waste into a plasma treatment unit; (ii) plasma treating the particulate metal-containing waste to form a layer of slag and, optionally, a layer of metal beneath the layer of slag; and (iii) recovering slag and/or metal from the plasma treatment unit; wherein the plasma treatment unit comprises an electrically conductive hearth for holding the layer of slag and optional layer of metal, one or more inlets for the particulate metal-containing waste arranged above the hearth, and an electrode arranged above the hearth so that, in use, a plasma arc is formed between the electrode and the hearth, and wherein the one or more inlets for the particulate metal-containing waste are arranged so that, in use, the particulate metal-containing waste introduced into the plasma treatment unit is heated by the plasma arc before contacting the slag layer. | 10-30-2014 |
20140066686 | TREATMENT OF WASTE - The present invention provides a method for the treatment of waste comprising one or more hazardous organic components, the method comprising plasma treating a waste in a plasma treatment unit; wherein the waste comprises: (i) a soil and/or aggregate material; and (ii) an oil component; and wherein, before plasma treating the waste, the waste comprises one or more hazardous organic components and from 5 to 50% water by weight of the waste. | 03-06-2014 |
