Abstract
The result of industrial tests of the technology super deep desiliconization of alumina liquors with fractional dose hydrocarboaluminate of calcium 4CaO×Al2O3×0,5CO2×11H2O. Due to this technology solution alumina liquors with higher silicon module (relative weight Al2O3/SiO2) without increasing lime carbonate expenditure.
