Apparatus for recovery of metallics and non-metallics from spent catalysts |
摘要 |
An electric arc furnace includes a crucible having a metal shell for recovering precious metals from spent material. The shell includes a metal tap hole and a slag door positioned above and opposite the metal tap hole. A removable swinging roof is provided above the crucible together with a plurality of electrodes for heating the spent material. Also, a cooling band circumscribes the crucible for cooling the metal shell. Conveyors are provided for distributing the spent material at a plurality of points located between the electrodes and the wall of the crucible. The crucible is tilted to allow the removal of the slag and metal.
