If it's pure zeolite.  I knew a guy that bought cat litter.  Where he lived
there was a pure zeolite cat litter.  He just powdered that and took it. 
Sounds nasty, lol, but it works the same.  If it's been cleaned of
contaminants, then it's all the same thing, just different sized particles.

You want to know if there are contaminants so you may want to call the
company where you found that.
