Iron ore Wikipedia

Available world iron ore resources. Iron is the most abundant element on earth but not in the crust. [citation needed] The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.

Ochre Wikipedia

Red ochre, Fe 2 O 3, takes its reddish colour from the mineral hematite, which is an anhydrous iron oxide. Purple ochre is identical to red ochre chemically but of a different hue caused by different light diffraction properties associated with a greater average particle size. Brown ochre, also FeO(OH),,is a partly hydrated iron oxide.
