Jan 01 2011 183 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 chemical leaching with sodium hydroxide sulphuric hydrochloric and nitric acids Although sulphuric acid is the most effective among the acids it suffers from a substantial loss of iron.
High alumina in the iron ore raises the levels of alumina in blast furnace slag To operate a blast furnace with high alumina slag is quite difficult and need a different type of skill from the blast furnace operators since with the increase in the Al2O3 content of the slag the blast furnace operation has problems such as excess accumulation.

Antifoams prevent foaming while defoamers suppress existing foam They are used to treat Bayer liquors in the alumina processing cycle including in the digesters precipitator trains hydrate classifiers mud washing circuits and cooling towers We offer s a variety of defoamerantifoam technologies to meet industrys needs across these.
By processing the aluminum ore the refined alumina can be used in many industries such as electrolytic aluminum ceramics medicine electronics machinery and other industries With the development of these industries the requirement of alumina is becoming larger and larger As we all know aluminum ore must be crushed before refining.
Aluminum is the most abundant metal in the earths crust and is a constituent of many minerals However the material which is highest in aluminum and most free from objectionable impurities is bauxite which therefore is practically the only source of the metal under present processes Bauxite is the general name given to the hydrated oxides of aluminum It contains varying amounts of.
Iron ore fines and slime contain 58 Fe high amount of alumina gt 8 and silica 8 Statistics showed that the increase in 1 Fe in the concentrate productivity of the hot metal increases by 2 and thereby coke and limestone requirements reduced by 18 and 09 respectively.
Bauxite ore is dissolved in sodium hydroxide or lye at a high temperature and pressure Then the alumina and bauxite ores are separated by washing out the waste red muds or sands from the alumina Finally hydrated alumina is crystallized and calcinated dried in a furnace to produce solid alumina.
