iron ore carbonaceous Solutions Just Right For You

Many meteorite hunters carry a diamond file with them to grind a small spot off rocks to see if there are any iron grains inside With only a few rare exceptions metallic iron metal is not found in earth rocks During eons of erosion and weathering the iron in earth rocks is now in mineral form and not metallic The metal found in meteorites will be shiny and look like chrome The appearance iron ore low -grade ore dolerite black shale mudstone and lignite revealed an overall significant enrichment of Se in these wastes when compared to mean crustal values Particularly elevated concentrations in samples of lignite (max 17 16 ppm) and carbonaceous "black" shales (max 4 07 ppm) indicate the prime geochemical association
