    Beneficiation of iron and aluminium oxides from fly ash at …

     · The disposal of the large amount of fly ash has become a serious environmental problem. Since it has significant amounts of iron oxide (6–15%) and aluminium oxide (20–30%), it may find use in the extraction and production of aluminium and iron oxides, and subsequently in the recovery of aluminium and iron metals.The fly ash was subjected to magnetic separation where part of iron oxide was separated. After this the fly ash was leached with hydrochloric acid followed by precipitating the leached liquor with ammonia hydroxide to get hydroxides of alumina and iron which are dehydrated at high temperature (1100 °C) to obtain iron and aluminium oxides as a mixed powder.Read more
