Hot dross from the furnace is collected in to a pan. The pan is shifted to dross processing machine by forklift/crane. Dross processing machine is a modified version of Universal Tilting Rotary Furnace. The major difference is that the door of the furnace is completely flush with the furnace and the door rotates with the furnace.

When all the dross is charged in to the furnace. The furnace door is attached with the furnace body and is detached with the door Colum. The furnace is ro-tated at a high speed which separate liquid aluminum metal from oxide. After the rotation the furnace tap hole which is located at the front end is open and liquid aluminum is tapped out by tilting the furnace upward. When all liquid metal is removed, the furnace is moved back to its original position and the door is removed from the furnace. Now all residual oxide with minimum amount of trace aluminum is collected in a pan for disposal .
