Mining a zeolitic ore is a relatively simple procedure if compared with other mineral commodities. Zeolite-bearing formations are generally at or close to the surface, and require the removal of only small amounts of overburden to expose the ore. The raw material only requires simple processes such as crushing, drying, powdering, and sieving.

Zeolite - Wikipedia

Zeolite-based oxygen concentrator systems are widely used to produce medical-grade oxygen. The zeolite is used as a molecular sieve to create purified oxygen from air using its ability to trap impurities, in a process involving the adsorption of nitrogen, leaving highly purified oxygen and up to 5% argon.
