Process for extracting and purifying naturally occurring zeolite

Abstract

A process for extracting and purifying naturally occurring zeolite from ores in the presence of other mineral phases by using mechanical dispersion and differential suspension to remove a majority of the clay content of the ore. The process continues by removal of contaminants with a higher mass to surface area ratio than that of the desired zeolite product by employing the properties of demineralized water in combination with a countercurrent flow separation column. No chemical flocculating or flotation agents need be employed in the process.

       55 . A process for separation of mineral phases from a natural mineral ore composition, comprising: 
 separating the mineral phases from an aqueous slurry or suspension by integrating differential suspension and physical separation principles, said aqueous slurry or suspension comprising mineral phases that have been substantially liberated from natural ore by crushing, grinding or milling and demineralized water with low electrolyte content that sustains a maximum electrical double layer to aid dispersal and separation of said mineral phases according to the extent of hydration.
