Setonian, it's iron oxide, not the metal (like gold). It's like rust stains you get in sinks from high iron in water. So it needs to be dissolved, maybe with a chelant (EDTA) in water and "washed" out with fresh water. Then you have to worry about disposal of the effluent, the whole process just adds cost to the final clay product. Far cry from the CEO loading up his pickup and making a delivery.
Cash is King until further notice!!!
My comments on companies are usually my opinion of long term success (years). The PPS may go up or down greatly in the meantime depending on the number of greedy suckers with money.
