  • Process for the removal of sulfur oxides by the use of activated alumina
    Patent number: 4075284
    Abstract: Production of an activated type alumina from aluminum dross by digestion with water, preferably pressurized. The peculiar properties associated with trace compounds present in the product make it useful for the recovery of noxious effluents from furnacing processes, including those burning fossil fuels and those used for smelting both aluminum and steel, wherein the alumina beneficially incorporates in the metallurgical flux.
