Metal, Iron, Nickel Some Meteorite

Because chondrites are rich in metal and the metal is rich in nickel, all chondrites have bulk (whole-rock) concentrations of nickel of 1.0-1.8% (i.e., 10000-18000 ppm). That’s 100-1000 times greater than practically any terrestrial (Earth) rock. An Earth rock with as much as 1.0-1.8% Ni would be a nickel ore. In terrestrial rocks the nickel is not contained in metal, however, but in ...

Platinum: The mineral native Platinum information

Natural Platinum is fairly impure. It is always associated with small amounts of other elements such as iron, gold, copper, and nickel, and may also contain the rare metals iridium, osmium, rhodium, and palladium. These impurities can lower its specific gravity to as much as 14, whereas pure elemental platinum is 21.4.
