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.
