Penny, I would suggest not relying on numbers of that scale, as I could not image there is a tangible market (must be highly specialised)

My understanding (DYOR) is
- detergent grade zeolites are around USD $400/t to 600/t (4A detergent builder) and
- molecular sieve grades (ie catalysts and absorbents) USD $2,000/t to $3,000/t depending on type (ie 3A, 4A, and 5A) and form (beads / pellets).

IMHO the above values would represent the bulk of synthetic zeolites sold commercially, although I imagine there maybe specific very low volumes types that sell for higher - but the market would be non-existent.

I think MSE would be happy with $400/t to $3000/t , if they can produced from kaolin and/or mine tailings at low cost using UQ technology.
