DROSRITE is a unique process that makes possible economic in-plant recovery of metal from hot aluminum dross. It is environmentally friendly, requiring no salt and producing no CO_2 or NO_x gases. The salt-free residues of the process are suitable for production of calcium aluminate or for other value-added use. The process is highly energy efficient, extracting process heat from energy in the residue and, thus, it does not require an external plasma torch, electric arc or fuel heat source. A DROSRITE pilot unit built by PyroGenesis has been tested with both black and white dross types. The unit was installed at two different aluminum plant locations, and tests were conducted for a total of six weeks "online" with hot metal holding furnaces where the dross was skimmed. Results of one of these industrial trials are presented, together with an economic analysis indicating cost savings on the order of 200 dollars per ton of dross treated.
