US20040101470A1 Process for filter aid production in

An improved process for the production of tricalcium aluminate (TCA) filter aid for use in an alumina refinery is described. Quicklime is slaked in a slaker tin using a suitable slaking solution to form a slaked lime slurry ( 10 ). A suitable surfaceactive agent is added to the slaking solution prior to slaking of the lime. Alternatively, the surfaceactive agents can be added to the slaked

The bauxite processed is low grade (31% recoverable alumina) by world standards and therefore generates 2 tonnes of residue for every 1 tonne of alumina produced. Worsley Alumina refinery was commissioned in 1984 with a rated capacity of 1 million tonnes of alumina and like all modern refineries uses the Bayer process.
