Native platinum is an exotic mineral specimen and an expensive metal. Unfortunately, well formed crystals of platinum are very rare and the common habit of platinum is nuggets and grains. Pure platinum is unknown of in nature as it usually is alloyed with other metals such as iron, copper, gold, nickel, iridium, palladium, rhodium, ruthenium and osmium.

Quartz. •••. Nastya22/iStock/Getty Images. Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.
In addition to platinum, this group includes iridium, osmium, palladium, rhodium, and ruthenium. While platinum is the most abundant, all these metals, except osmium, have jewelry applications. Rhodium frequently sees use as a non-tarnishing plating for white gold, silver, and other platinum …
Mineral Resource of the Month: Platinum Group Metals . by U.S. Geological Survey . Thursday, June 14, 2018. Patricia J. Loferski, a mineral commodity specialist for the U.S. Geological Survey, compiled the following information on platinum group metals, used mainly in automobile catalytic converters.
White gold was originally developed to imitate platinum (a naturally white metal). White gold is usually an alloy containing about 75% gold and about 25% nickel and zinc. If stamped 18 karat, it would be 75% pure gold.
When platinum is found in a pure state, it is called native platinum. The Ural Mountains are well known for their rich mineral deposits. Over the last few centuries mining has varied from small-scale family operations to large mining conglomerates. In contrast to gold, platinum …

Platinum and palladium are found with gold in ores of the Boss mine, in the Yellow Pine district, Clark County, near Moapa, in eastern Nevada. The ore minerals here are associated with quartz that replaces dolomite along vertical fractures. Granite porphyry intrudes the dolomite, and no basic igneous intrusive rocks are known in this region.

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 by the sulfide minerals. Several gold tellurides are known, but no gold selenides have been reported, and only one sulfide, the telluride-sulfide mineral nagyagite, ii:; known.
The platinum occurs here with gold in placer deposits, and, while the fields are not largely productive at present, they may become so. The only platinum found in the United States came from the gold placer deposits of Alaska, Oregon and California. Return to the Mineral Collectors Information Page. Natural Platinum Crystals

Platinum is always found alongside other PGMs. 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.

Platinum nuggets are actually MUCH rarer than placer gold nuggets are. Nearly all of the platinum found around the world is microscopic bits that are extracted from the ores, and not large enough to be captured by traditional placer mining methods. The largest source of platinum is South Africa. Recently a mine in the state […]
The first documented discovery of platinum was by the Spaniards in the 1500s, in the alluvial gold mines of the Río Pinto, Colombia.They called it platina del Pinto, from platina, which means "little silver," thinking that it was an impure ore of silver.

A GOLD-PLATINUM-PALLADIUM LODE IN SOUTHERN NEVADA. By ADOLPH KNOPF. INTRODUCTION. The discovery of platinum-bearing 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.
Platinum is a good catalyst to use in chemical reactions. South Africa is the number one producer of platinum metal. Gold vs Platinum. Platinum has the atomic number of 78, and atomic number of gold is 79. Platinum, most commonly, forms +2 and +4 oxidation states, but gold commonly forms +1 and +3 oxidation states.

In addition to gold bearing sands, deposits of platinum are often found in outcroppings of plutonic rocks like olivine and chromite. The formation of these rocks are a testament to platinum's pedigree, as all were exposed to extremely high temperature and pressure in order to produce this most valuable of metals.
