DROSRITE PLUS? TREATMENT OF ALUMINUM AND ZINC DROSSES

摘要

In both the hot rotary-salt-furnace (RSF) treatment of aluminum dross and the cold ball-mill-sieving (BMS) treatment of zinc dross, enormous amounts of energy and recoverable metal are wasted and large amounts of greenhouse gas are produced. Such wastes and the environment pollution could be avoided by using the DROSRITE PLUS? technology. Economic and GHG production comparisons between the presently used industrial treatment processes and DROSRITE PLUS?, supported by over one hundred tests conducted in Canada, the US and Europe, are presented. The savings, with DROSRITE PLUS?, would be about $191 and $418 per MT of aluminum and zinc dross, respectively.
