Come on 924T - four good guys on this forum tell you not to bother and still ypou say "I'm gonna do it." Seriously mate- you could make more going to a junk fair.
That's not the point. Processing such material offers good learning experiences.
Education isn't free. It comes with a price---with the attempt to extract the platinum being a small price to pay to experience how platinum behaves.
My attitude? Do it for the experience. That, in and of itself, will provide the knowledge to process similar material in the future, and the wisdom to decide if it should, or should not be processed.

I should, perhaps, be much more clear: I heartily advise against doing this lot for the experience--not only is there no net economic return, there are the following reasons:
1. Large amounts of dilute Pt(IV) solution create a contamination hazard
2. Gross excess of chemical needed for very small yield.
3. Limited contaminants present mean there's not much to separate any Pt from so little utility is gained
Much rather, start with some jewelry findings or a ring and beat it flat. Then you can learn about how difficult it is to dissolve, and learn the more complicated task of separating it from iridium. It also gives more concentrated solution that is easier to work with.
