how to suppress alumina in iron ore washing
can silica and alumina be removed from iron ore by washing It is essential that the Al2O3 (alumina) be obtained substantially free from these impurities as otherwise the iron oxide and silica would be reduced and contaminate the metallic aluminum produced in the Hall (or Heroult) Process The separation of the alumina from the impurities in 1/1/2011 Alumina and silica can be selectively removed from iron ore rejects slime by leaching with sodium hydroxide whereas leaching with mineral acids dissolves significant amounts of iron oxides Sodium hydroxide simultaneously removed alumina, silica and phosphorus with negligible loss of iron This reaction is sensitive to the concentration of NaOH and temperature as well as the flow velocity of The removal of alumina and silica from iron rejects slime Abstract A hydrometallurgical method of alumina and silica gangue removal from rejects slime of iron ore by alkali and acid leaching is proposed Up to about 80% gangue is removed by chemicalThe removal of alumina and silica from iron rejects slime
