The general consensus on platters is:

1. 20 grams per ton for platter weight only (not all platters contain platinum, testing is required to determine which do).

2. The labor and chemical costs involved do not warrant recovery. Sell them as aluminum.

You can search the forum for lots of information on this topic.
