Abstract
Peptisable natural aluminum hydrosilicate organo complexes are separated from water-insoluble organic and/or inorganic mineral materials and from natural aluminum hydrosilicate organo complexes that cannot be peptised in water, by milling mineral materials such as clay or brown coal to a size smaller than 60 microns, vigorously mechanically agitating the mixture at 60 to 120.degree. C. so as to dissociate the same to the colloidal state, during which the hydrophilic binding positions of the material are loosened by hydration, and finally separating the thus-formed peptised solution from insoluble material. The solution may be concentrated and the insoluble material itself is useful because of increased calorific value and higher specific surface area. Peptisation may be carried out in the presence of peptising agents such as ammonia-soda, Na.sub.2 CO.sub.3, NaOH, KOH, or cetyl-pyridine-chloride, in an amount up to 5% by weight.
