FIELD: hydraulic metallurgy, possibly alumina production at conversion of decomposition of aluminate solution. ^ SUBSTANCE: method comprises steps of hydraulic separation of hydroxide pulp for producing discharged products containing fine fraction of hydroxide and condensed hydroxide containing large fraction; condensation of discharged products; transporting condensed hydroxide after its hydraulic separation to one agitator, then to filtration and transporting hydroxide after condensation of discharged products to other agitator, then to filtration and repulping. ^ EFFECT: enhanced efficiency of alumina production due to improved sorting of aluminum hydroxide by fraction size. ^ 4 cl, 1 dwg |
