Abstract
The production of zeolites from waste, for use in detergents comprises mixing of filtered pickling liquors with caustic soda and e.g. soluble silicate, in specific proportions. Nucleation, aging, crystal growth and separation of the solid product are then controlled. The presence of organic suspended products of decomposition of the gluconates extending the process bath life, requires preliminary filtration for effective zeolite production.
