Both palladium and platinum are distinctly lower than in average ore from the Merensky Reef. Palladium ranges from 5,000 ppb in highgrade massive ores with 20 weight percent nickel to ppb in unmineralized ultramafic rocks; iridium varies from 1,000 to 3 ppb in the same rocks.
Gold: A test known as Darton''s is believed to be a valuable means of detecting minute quantities of gold in rocks, ore tailings, etc. quot;Small parts are chipped from all the sides of a mass of rock, amounting in all to about | ounce. This is powdered in a steel mortar and well mixed. About half is placed in a capacious test tube, and then the tube is partly filled with a solution made by
Its annual platinum production is nearly million worth more than billion in value. Apart from being the largest platinum producer, Anglo American is also one of the worlds major producers of base metals (copper, nickel, cobalt sulfate, sodium sulfate, chrome) and largest gold producers. 2, Impala Platinum
Gold occurs in nature mainly as the metal and as various alloys. It forms complete series of solid solu#173; tions with silver, copper, nickel, palladium, and platinum. In association with the platinum metals, gold occurs as free gold as well as in solid solution. The native elements contain the most gold, followed

Back to Rocks and Minerals Articles Kathy Feick Platinum is among the rarest and most expensive of the popular precious metals. Natural platinum is fairly impure. It is always associated with small amounts of other elements (gold, copper, nickel and iron) and commonly contains the rare metals platinum, palladium, rhodium, iridium, osmium and ruthenium.
A GOLDPLATINUMPALLADIUM LODE IN SOUTHERN NEVADA. By ADOLPH KNOPF. INTRODUCTION. The discovery of platinumbearing gold ore at the Boss mine, in southern Nevada, was brought to the attention of the Geological Survey by Mr. F. A. Hale, jr., in September, 1914. Some samples of the ore were submitted at the same time.
In the alluvial deposits of the Urals, platinum is sometimes found associated with gold, and sometimes without gold. It is noteworthy that platinum is an original mineral formed in some peridotites; and in the Urals, where no gold occurs in the platinumbearing gravels, these gravels can be seen to have been derived from peridotite or serpentine and the associated basic rocks.
A group of mineral deposits found in Wyoming contains platinum group metals and nickel. These produced at least 6,100 tons of copper ore with gold, silver, platinum, and palladium (McCallum and Orback, 1968). The U several other rock types in the district host auriferous shears suggesting more than one source rock contributed 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
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
#0183;#32;Platinum(IV) by contrast is more nearly classa in character and is frequently reduced to Pt II by P and Asdonor ligands. The organometallic chemistry of these metals is rich and varied and that involving unsaturated hydrocarbons is the most familiar of its type.

Gold and silver is often found in the same ore, Most gold mines are also producing silver, silver mines often produce also copper. platinum is mostly mined single but that doesn''t mean that there aren''t other metals in the ore but just not economic to further process the ore.
