My personal experience with silver in an industrial environment

Gary I am saying that 10% is unrecoverable because it is not there anymore or not worthwhile to recover due to cost. That could mean that the 10% is still left in the carrier that is discarded, but is not economically feasible to recover it. The 10% lost could have also been lost by the nature of the EO process so, in essence, the 10% was lost before it could even be reclaimed. I'm thinking it is probably a combination of these 2 yield losses. Hope this helps.

Medoraman is correct in that the catalyst is never "consumed". It either combines with other elements such as oxygen or is blown off the catalyst and ends up elsewhere down the line. I'd bet that if a test could be conducted we would find silver in the ppm, ppb, or ppt range in the finished product.

That clarifies it some. Basically, I had the concept.
