Abstract
The filtration of zeolites, for example sodium alumino silicates, from aqueous slurries containing the zeolites is improved by washing the filter cake with an aqueous solution of any salt which has the capacity to produce a stabilized slurry of the zeolite. Suitable salts include alkali metal carbonates, bicarbonates, sulphates and salts of organic acids.
