that there is 14 mg of Pt (NO Pd, Rh, etc.) per unit. However, I know certain refiners have been paying more than that value per unit.
As far as processing them yourself, you'll have to find a way to free the zirconium cone onto which the Pt is plated, and this is no easy task. That is the only part of the O2 sensor which has PM value.
