Abstract: The efficiency of roasting black dross can be improved by pre-processing the black dross before roasting. Black dross can be crushed and reconstituted into pellets having internal channels. The internal channels can be filled with additives designed to fully oxidize during a dross roasting process, enabling the internal channels to be open and gas to flow therethrough during a dross roasting process. The crushed black dross can be crushed to pieces below 10 mm and screened for larger pieces prior to pelletizing to ensure consistent pellets. Optionally, an eddy current separator can remove some metallic aluminum from the crushed black dross prior to pelletizing.

Abstract: Salt components of dross can be extracted efficiently through evaporation. During dross treatment, temperatures can be permitted to approach or exceed the boiling point of one or more salt components of the dross, preferably in an oxidizing environment. The temperature can be held sufficiently high such that the salt content can exert an appreciable vapor pressure and can be held for a sufficient time to permit most, all, or substantially all of the salt content to evaporate and be carried away from the kiln in combustion gasses. The evaporated salt can be condensed and collected.

Abstract: A two stage dross treatment capable of being performed in a single reaction vessel is disclosed. Dross, especially white dross, can be contacted with salt flux in a rotary furnace to recover metal from the dross. This first stage can recover metal during the conversion of white dross and salt flux to salt cake. In a second stage, the furnace can be raised to a sufficiently high temperature to evaporate the salt content of the salt cake, allowing the evaporated salt to exit the furnace and be separately condensed and collected. The result of the second stage is collected salt and salt-free oxides. After removing the salt-free oxides, residual heat in the furnace and collected salt can be used for a subsequent dross treatment.

Abstract: The invention is a device which receives radiation from a point source, from the sun, or from other means, said radiation being received on the surface of a mirrored paraboloid of revolution which is tracking the point source, though the source may be stationary, and reflects the radiation to the mirrored surface of a confocal hyperboloid of revolution whose shape is dependent on the distance to the desired second focus. The hyperboloid reflects radiation of high intensity to the second focus, where the flux is intensified, using a conical mirrored surface or a compound parabolic concentrator, to a flux intensity approaching the surface flux intensity of the sun. The radiation input to the device may also be from an array of point or distributed sources, such as from an array of lasers.
