He also explained to me that he wanted to get a furnace for himself so that he could just melt out the alluminum from the platters since the platinum has a much higher melting point. Said something to the affect of putting 100 spindles in at a time. Now what research I have been able to do so far tells me that a platter is about 2% platinum/palladium by weight. The trick is extracting it in a cost affective way. Ill let you know if anything comes of it. I just found it interesting is all.
That is not going to work too well. When he you try to melt the aluminum it will lower the melting temp of the PD & PT and they will alloy with the aluminum.



I would remove the AL with HCL and then process the foils or melt them with silver as an accumilator and then process the silver and process the PT & PD slimes after that.
