<p>[QUOTE=&quot;medoraman, post: 997237, member: 26302&quot;]Catalysts vary a lot in the amount recoverable. I have read a lot of platinum catalysts, and understand that in some processes the entire amount of platinum is lost, in some only a portion, and in others it never is lost. Theoretically of course a catalyst is never lost, but in production realities there usually is and that is why I asked about it. I am sure in platinum catalysts it would be worthwhile to take further measures to reduce loss, but some is unavoidable. Basically in the platinum article I read they detail the movement away from platinum as prices rose, specifically in those industries where loss was heavy and unavoidable. Most of those industries use palladium or another platinum group element now.</p><p><br /></p><p>I think gave Swagge some excellent examples of losses that can be experienced in production, even though theoretically a catalyst is never &quot;consumed&quot;.[/QUOTE]</p><p><br /></p>
