METHOD OF BAUXITE LEACHING

摘要

production of alumina; applicable in process of bauxite autoclave leaching. SUBSTANCE: method consists in continuous pumping of bauxite pulp through regenerative heater, autoclaves and leached-pulp self-evaporators; heating of water with heat of leached pulp for slime washing. Regenerative heating of pulp is carried out in two alternating regimes: steam-pulp and steam-pulp-pulp. EFFECT: higher technological potentialities of method. 1 dwg
