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.
