METHOD FOR SEPARATING ALUMINUM HYDROXIDE OUT OF SOLUTION Russian patent published in 2005 - IPC

Abstract RU 2256616 C2

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.
