There are very few true gold ores, besides native gold, because it forms a major part of only a few rare minerals, it is found as little more than a trace in a few others or it is alloyed to a small extent with other metals such as silver. Gold is almost indestructible and has been used and then reused for centuries to the extent that all gold of known existence is almost equal to all the gold
Most silver is extracted from silver ores, but considerable amounts are mined from Native Silver. Silver can be found pure, but is usually mixed with small amounts of gold, arsenic, and antimony. A natural alloy of gold and silver is known as Electrum, and is usually classified as a variety of Gold. Silver is a very resistant mineral.
Much of the Gold mined is from large mining operations where the Gold is smeltered for commercial use, and although many commercial gold mines exist, mineral specimens and crystals are hard to come across. China and South Africa have been the worlds two largest Gold producers, but collectors will rarely if ever see a Gold specimen from these countries due to the restrictive nature of the
The most common gangue minerals containing gold are: quartz, carbonates, chlorite, graphite (including other carbonaceous material), and tourmaline. Many other minerals are occasional hosts for gold. Available data suggest that few minerals are effective precipitants of gold under natural conditions although the possibility of precipitation of gold by the host mineral is not denied

Native Platinum is the most significant source of the element platinum, although considerable quantities are also mined from the rare platinum arsenide mineral Sperrylite. The rare metals iridium, osmium, rhodium, and palladium are almost exclusively mined together with platinum in platinum deposits.
Gold Mineral Facts: Chemical Formula: Au . Colors: The mineral is various shades of metallic yellow, depending upon purity, becoming paler with increase in the percentage of silver present. Hardness: to 3. Density: to Density varies somewhat depending on impurities the purer the heavier.
Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties some of which are unique to gold.

Gold is a soft metallic element. Its symbol is Au. It is very dense. As one of the noble metals it is resistant to corrosion and oxidation in moist air. Copper is a soft metallic element. Its symbol is Cu. Native copper is rare because it has been mined for centuries. Today it is used for making wire, tubing, and coins to name a few. Long ago it was combined with tin to create bronze.

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 telluridesulfide mineral nagyagite, ii:; known. The nonmetallic minerals carry the least gold, and the lightcolored minerals generally contain less gold
