hi all,
im getting this cat material for 100$ per kilo
is it the right price to pay?
i calculated per kilo should have (236 mg of pt, 1.2g of pd, 428mg of rh)
that about 200$ worth of metal give or take
i have a refiner who is willing to pay 97% of all metals

please correct me if i'm wrong.
thnks.

The rhodium amount seems exaggerated - expected 0.1 g

hi lino1406, thanks for your reply
any other way to check the value?
xrf was done 2-3 times

XRF is reliable on metallic melt, so get the assay in this form
