Abstract
An apparatus and method are described for recovering metal from dross. The apparatus comprises a chamber having an opening to receive the dross and an agitating member mounted in the chamber. The agitating member is driven so that it agitates the dross in the chamber so as to release the metal from the oxide of the dross. The chamber also has an outlet through which the recovered metal and residual oxide are discharged.
Claims12
An apparatus for recovering metal from metal/oxide dross the apparatus comprising:
- a chamber, means to allow dross to be placed in the chamber, an agitating member mounted in the chamber, means for driving the agitating member so that it agitates the dross in the chamber so as to release the metal from the oxide of the dross, means to allow the released metal and the oxide to be removed from the chamber, a receptacle for receiving metal and oxide which has been removed from the chamber, and means for separating out an oxide layer from the metal on which the oxide floats in the receptacle.
An apparatus for recovering metal from metal/oxide dross, the apparatus comprising:
- a tubular member having a generally horizontal axis, the tubular member having an inlet opening for receiving dross and an outlet opening spaced apart from the inlet opening along the tubular member;
- a rotary shaft extending along the tubular member and having a generally horizontal axis;
- means for rotating the shaft in a predetermined direction;
- and a plurality of vanes mounted on the shaft for agitating dross received through the inlet opening as the shaft is rotated to release the metal from the oxide of the dross the vanes being inclined relative to the axis of the shaft so as to urge the dross, metal and oxide along the tubular member towards the outlet opening as the shaft is rotated in said predetermined direction so that the metal and oxide exits the tubular member through the outlet opening.
