Nickel Platinum And Gold Ore In Rock

Palladium, iridium, and gold in the ores and host rocks of ...

The total precious metal tenor of typical Western Australian nickel sulfide ore is similar to that of average Sudbury ore although gold, ruthenium, iridium, and osmium are higher (and platinum may be lower) in the Western Australian ores. Both palladium and platinum are distinctly lower than in average ore from the Merensky Reef. Palladium ranges from 5,000 ppb in high-grade massive ores with ...

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 ...

List Minerals Associated with Gold

To know what type of rock is gold associated with you must see that the minerals most common in placer deposits are platinum, iridosmine, magnetite, iron pyrites, ilmenite, zircon, garnets, rutile and barytes; wolfram, scheelite, brookite and diamonds are less common. Diamonds are associated with gold in Brazil, and also occasionally in the Urals and in the United States. In auriferous quartz ...

2020-04-26  North of the Lake Owen complex in the Centennial Ridge district, late 19th Century mine developers cut mafic metaigneous rock in search of gold associated with platinum-group metals. The mineralization is spotty and found in shears and veins. The richest ores were found in sulfide-rich zones in mafic mylonites, graphitic fault gouge, and in strongly chloritized zones (McCallum, 1968).

Platinum: The mineral native Platinum information and pictures

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.

The Properties and Applications of Platinum

2020-08-21  In South Africa's Bushveld complex and a limited number of other ore bodies, PGMs occur in sufficient quantities so as to make it economical to exclusively extract these metals; whereas, at Russia's Norilsk and Canada's Sudbury deposits platinum and other PGMs are extracted as by-products of nickel and copper. Extracting platinum from ore is both capital and labor-intensive. It can take up
