Red mud waste from the aluminium industry was modified by leaching using hydrochloric acid or oxalic with additives, followed precipitation evaporation. The prepared catalysts were characterized in detail and tested for toluene total oxidation. samples of leachate adding a base gave much better performance catalytic oxidation than ones just evaporating leachate. These improved performances can ...

Red mud is a strong alkaline waste discharged from the process of alumina extraction, which harmful to environment and its utilization rate always low. One effective ways utilize red used as road subgrade material. In this paper, industrial wastes including mud, fly ash, slag, desulfurized gypsum are basic raw materials prepare filling materials. A series laboratory tests, such compaction test,...
