There are some things I need to know about the PGMs from cats before I buy the expensive equipment.
What is the approximate purity of the PGMs in %, extracted from cats using Steve's way? What are the impurities?
Is it necessary to use hydrogen torch for melting the PGMs? I can not find any in my country
How bad will it be if I use propane/O2 torch? Will it be better if I use a home made mini-firebrick furnance with a PGM melting dish inside and a propane/O2 torch (or maybe two of them :twisted: )?

If you can run an oxidizing flame, you can get by with alternate fuel sources. Try to avoid a reducing flame, which has the tendency to produce carbides.
