	Reference.com/Encyclopedia/Platinum group
		The platinum group (alternatively, the platinum group metals or platinum metals) is a collective name sometimes used for six metallic elements clustered together in the periodic table.
		Platinum, platinum alloys, and iridium are used as crucible materials for the growth of single crystals, especially oxides.
		Platinum in a native state, often accompanied by small amounts of other platinum metals, is found in alluvial and placer deposits in Colombia, Ontario, the Ural Mountains, and in certain western American states.

	Platinum - Wikipedia, the free encyclopedia
		Platinum was discussed by astronomer Antonio de Ulloa and Don Jorge Juan y Santacilia (1713–1773), both appointed by King Philip V to join a geographical expedition in Peru that lasted from 1735 to 1745.
		Platinum is often found chemically uncombined as native platinum and alloyed with iridium as platiniridium.
		As platinum is a catalyst in the manufacture of the silicone rubber and gel components of several types of medical implants (breast implants, joint replacement prosthetics, artificial lumbar discs, vascular access ports), the possibility that platinum free radicals could enter the body and cause adverse effects has merited study.

	Encyclopedia: Platinum group
		The platinum group or platinum family is a group of six (Any of several chemical elements that are usually shiny solids that conduct heat or electricity and can be formed into sheets etc.) metal (Violent or severe weather (viewed as caused by the action of the four elements)) elements with similar physical and chemical properties.
		Platinum is often found in a native state and the (A metal-bearing mineral valuable enough to be mined) ore sperrylite (platinum arsenide, Pt (A very poisonous metallic element that has three allotropic forms; arsenic and arsenic compounds are used as herbicides and insecticides and various alloys; found in arsenopyrite and orpiment and realgar) As
		Platinum is also produced commercially as a by-product of (A hard malleable ductile silvery metallic element that is resistant to corrosion; used in alloys; occurs in pentlandite and smaltite and garnierite and millerite) nickel ore processing.

	NATIVE PLATINUM (Pt)
		Platinum's origin in the crust is from ultra-mafic igneous rocks and therefore platinum is associated with minerals common to these rocks such as chromite and olivine.
		Over the ages, the platinum became weathered out of the igneous rocks and were tumbled down streams and rivers where the extremely heavy grains and nuggets of platinum collect behind rocks and bends in the rivers and streams.
		Native platinum is the primary ore of platinum, but deposits containing the rare platinum arsenide, sperrylite of the Pyrite Group, have made a huge contribution to the world's limited supply.

	Mineral Information Institute - PLATINUM GROUP (Site not responding. Last check: 2007-10-29)
		Platinum Group Metals (includes platinum, palladium, rhodium, iridium, osmium, and ruthenium): they commonly occur together in nature and are among the most scarce of the metallic elements.
		Platinum is used principally as catalysts for the control of automobile and industrial plant emissions; as catalysts to produce acids, organic chemicals, and pharmaceuticals.
		It belongs to a group of elements that are in the second and third triads of Group VIII of the Periodic Table of the Elements.

		These elements are all transition metals, lying in the d-block (groups 8, 9, and 10, periods 5 and 6 — in Mendeleev's original table, this area was called "Group VIII").
		The huge quantities of nickel ore processed makes up for the fact that platinum makes up only two parts per million of the ore. South Africa, with vast platinum ore deposits in the Merensky Reef of the Bushveld complex, is the world's largest producer of platinum, followed by Russia.
		Even though the quantity of platinum metals found in these ores is small, the large volume of nickel ores processed makes commercial recovery possible.

		Importantly, the platinum to palladium ratio of the newly discovered zone is almost 1 to 1, making the new zone a highly desirable economic target.
		The Seagull platinum reefs are also characterized by higher values for the rare PGE elements osmium and iridium than those generally observed in the famous Merensky Reef of South Africa.
		Michael Jones, President of Platinum Group Metals Ltd., said "In our view this is one the most significant new occurrences of platinum group elements in North America and it is very exciting to use our active South African experience on a reef discovery near Thunder Bay, Ontario.

	American Metal Market: Japan jewelry trade supports platinum - Platinum Group Metals
		It is unusual that platinum which was valued at $100 per ounce more than gold has dipped to less than the gold price in recent months, industry executives said.
		The survey of 80 platinum firms showed the majority anticipate sales increases of up to 10 percent during the latter half of this year, with the largest increase expected for platinum pendants.
		One major trader is projecting platinum imports to Japan during the year ended March 31 as 61 metric tons, or 1,961,226 troy ounces, an increase of 1.7 percent from the 60 tons imported in the previous year.

	Concentrations of Platinum Group Elements in 122 U.S. Coal Samples
		A second group of 62 samples, primarily from the major coal producing areas, was selected for broad geographic coverage and to represent various coal ranks and coal-associated materials (coal waste, limestone, claystone, etc.).
		A third group of 7 coal samples was chosen because of the relatively high concentration of elements (such as Cr, Co, Ni, V, Ag, Pb, total sulfur, pyritic sulfur) that may be associated with PGE due to thier geochemical properties (Goldschmidt, 1954).
		A fifth group of 37 samples was picked on the basis of their carbon, hydrogen, nitrogen, and oxygen ratios representing mostly cannel coal samples (initial results indicated higher concentrations of PGEs in cannel coals than in banded coals).
