Abstract
Procedure for obtaining alumina of metallurgical purity, by treatment of silico-aluminous materials containing Ti and Fe and less than 0.1% K2O, which includes a sulfuric attack on the mineral, the separation of the attack residue and the liquor from attack, the treatment of the attack residue, firstly by a displacement wash with the reunification of the displaced mother liquor and the attack liquor, and then the washing with water of the precipitate, obtaining AlCl3, 6H2O by addition of gaseous HCl to a solution containing dissolved AP2 (SO4) 3, the calcination of the chloride and the recycling of the effluents, the treatment of the liquor resulting from the washing of the attack residue, characterized in that the starting silico-aluminous matter is introduced into fine particles in a recycled solution containing by weight 49 to 59% free H2SO4 and 6 to 8% (NH4) 2S04 and containing residual amounts of various sulfates, because the suspension thus obtained is heated for 1 to 5 hours between 135ºC and 125ºC, because the liquor resulting from the attack is concentrated and cooled to precipitate an aluminum acid sulfate of formula (Al) 2 (SO4) 3, 0.5 H2SO4, 11 to 12 H2O, because This precipitate, after washing, is contacted with a concentrated solution of HC1 to constitute the solution or suspension to which the HCl gas is added, because the mother liquor resulting from the crystallization of the acid sulfate is used in part to displace the mother liquor that impregnates the attack residue and is added, in the other part, to the liquor resulting from the washing of the attack residue with water, because the liquor mixture is subjected to evaporation and is then kept at 80ºC for 2 to 3 hours to cause the precipitation of a complex iron, titanium and ammonium sulfate, which then decomposes into solid elements that are eliminated and into gaseous elements that are recycled.
