A dross processing system has a substantially vertical support positioned in close proximity to a furnace. A reaction vessel is mounted to the substantially vertical support by a reaction vessel support. The reaction vessel preferably has a substantially vertical sidewall and a bottom member having a sealable port. The reaction vessel is preferably fabricated of stainless steel sheet stock, and can have expanded metal sheet welded to the outside or can have a dual-shell structure. The reaction vessel is retained in a horizontal position for loading metal-bearing dross, and can pivot to dump spent dross. The reaction vessel support can be rotatably mounted with respect to the furnace to allow the reaction vessel to be swung away from the furnace for dumping. In one embodiment, the reaction vessel can also be raised and lowered. A motor having a drive shaft with a free end is connected to a motor arm which in turn is mounted with respect to the substantially vertical support such that the motor can be raised or lowered. Preferably the motor can be translated and can be secured in multiple lowered positions. An impeller attaches to the free end of the drive shaft and is positioned below the upper rim of the reaction vessel when the motor is in its lowered position. A protective shield which engages the upper rim of the reaction vessel to contain fumes when the motor is in its lowered position is preferably also provided.
