<p>[QUOTE=&quot;Conder101, post: 1378951, member: 66&quot;]I would imagine the easiest way would be first to use a furnace to burn off the organics.&nbsp; Then pound the ash into dust.&nbsp; Boil the dust in nitric acid for awhile.&nbsp; Drain the acid off and set aside for later precipitation of the base metals and silver.&nbsp; Boil the residue in aqua regia to dissolve the gold and platinum group metals.&nbsp; Filter the residue.&nbsp; The residue is your inorganics and then you recover and refine the gold and platinum metals from the aqua regia.[/QUOTE]</p><p><br /></p>
