Abstract
As part of the hydrochloric acid technology elaboration for processing of non-Bayer raw materials to alumina the conditions of acid leaching of Siberian non-bauxite aluminous ores were studied. Based on the minerals’ structure the mechanism of aluminum transition to acidic solutions was suggested. The conditions of the acid leaching process which required for different kinds of aluminum raw materials were determined.
The phenomenon of silica and titanium partial dissolution with subsequent transformation to colloidal form as a result of aging is found. The methods of artificial ageing of such liquors and slurries are suggested to produce sufficiently filterable residues.
