I disagree...... Platinum may be 3x more common than gold in the earth crust but its diffusely distributed with very few concentrated deposits so in reality it is 20x more rare than gold in a form that can be mined. Similarly Pd is 2x as rare as gold but has slightly more concentrated deposits as Pt, so mining deposits are very similar to Pt. much more rare than gold.... Of the total Pt and Pd supply there is almost 1 year stockpile of Pd (5 mill oz) in private hands and far less than half that in Pt.The owners identity is pretty secret. The current shortfall of 0.5 mill oz of pd is made up by release from stockpile. Pt is less well defined. Russian Pd and Pt mining is at historic low and we all know about SA. That is 90% of PGM production. Pt mining and refine costs are currently at US$1700 /oz -it is the best PM to buy....
You can disagree but the question was "Wonder how much of it is left?" Platinum is 25% more abundant than Gold according to "It's Elemental The Periodic Table of Elements". Jefferson Lab. Archived from the original on 29 April 2007. Retrieved 2007-04-14." Silver is found in the earths crust at a rate of 0.075 ppm Gold is found in the earths crust at a rate of 0.004 ppm Platinum is found in the earths crust at a rate of 0.005 ppm ppm = (parts per million); Data sourced from http://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth's_crust "^ Barbalace, Kenneth. "Periodic Table of Elements". Environmental Chemistry.com. Retrieved 2007-04-14." has it at almost triple
Clearly you did not read what I wrote---- although it is more common in ppm it is far more rare than gold in mineable deposits.... How big are the stockpiles - easy bugger all... There is a year of Pd stocks that can be used in cat converters but require twice as much metal... Not for diesel though
Maybe you didn't read mine "A lot, it's 25% more abundant than Gold, just really difficult to mine and even harder to refine"
Anyone know how to get to parts 2 and 3 - the infographic doesn't link it and the original site does not mention it.
Part 2 is here ... http://www.perthmintbullion.com/au/Blog/Blog/13-09-12/Infographic_Platinum_Supply_And_Demand.aspx I think that Part 3 hasn't been published yet.

A few more facts about platinum metals that may help you identify Pt, Rh, and Pd scrap when out an about: Platinum group metals are unaffected by most acids that are used to test PM's, because of this most high street jewelers and pawn shops won't buy it as they can't positively identify it! Nitric and Hydrochloric do nothing at all unless the metal is impure when most industrial Pt metals are 999 purity or better. Pt can be alloyed with cobalt in jewellery giving a blue tinge to the acid when applied to the test piece. Pt Group metals also don't tarnish when subjected to 1000c+ temperatures remaining bright and shiny unlike most metals which oxidise and tarnish. Wind proof gas Cigarette lighters are good for this test on small pieces like wire.
