WATER TREATEMENT USING A CRYPTOCRYSTALLINE MAGNESITE - BENTONITE CLAY COMPOSITE

摘要

A process for the treatment of contaminated water includes contacting the contaminated water with a cryptocrystalline magnesite – bentonite clay composite thereby to remove one or more contaminants from the water. The invention extends to a method for the manufacture of a cryptocrystalline magnesite – bentonite clay composite wherein an admixture of cryptocrystalline magnesite and bentonite clay is milled to a desired particle size with amorphization of the magnesite and bentonite clay in the resultant cryptocrystalline magnesite – bentonite clay composite, and to a cryptocrystalline magnesite – bentonite clay composite.
