Depending on the pallasite (is the cost of rehabilitation worth it) and the extent of rust damage, you can pursue different options. If there is rust between the olivines and iron, you will likely have to use an electrolytic process. KD Meteorites are the experts in doing this. If it is just a

Resending see my opinion below interpreting your question to deal with extracting the olivines by consuming the metal matrix. Sent from AOL Mobile Mail -Original Message--- I have never wanted to consume an iron meteorite, but if I did, I would buy some inexpensive 37% (concentrated)

The very thought of it makes me cringe. The chances of getting crystals worthy of gem-stones, is slim. IMHO it would be sacrilege to destroy one of the most beautiful meteorite types, for a few gems and a little cash.  On 09/20/16, Gmail via Meteorite-list

Francesco, I am obviously in the minority, but I thought you wanted to keep the pallasite whole and just wanted to get rid of rust. Re-reading the email, it does seem that you may want to dissolve the iron to extract the olivines. If you want to extract the olivines, be aware that whatever

Francesco and All, I understand where you're coming from. You have a pallasite slice/end cut that apparently was not cut properly. By that I mean, the final prep work so you have some moisture trapped inside the item which has led to rust developing between the iron/nickel and the olivine/peridot.
