The most prominent is native gold - most of the native gold contains a small amount of silver, copper, platinum, etc. Telluride minerals are the most common minerals which contain significant gold in their make up. They include: Petzite (Ag,Au) 2,Te, with a gold content of about 25 per cent.
1. Quartz gold ore Quartz gold ore properties Gold exists in quartzite. Usually, quartz appears as small stones in large cracks in riverbeds or mountain slopes and has crystals in different colors such as white, yellow, pink, purple, gray, or black. The most common types of quartz with gold ore are rose quartz gold ore and rainbow gold ore.
Blaize asks: I broke a marble/quartz?-looking rock and found a whole bunch of shiny flakes. They are small but they look almost like gold. Some are more silver in colour. Do you know what they might be? Can you help? « Last Edit: 29/07/2017 18:34:18 by chris »
Quartz -sulphide gold ± copper Quartz -sulphide gold ± copper deposits, which form at deepest crustal levels close to porphyry intrusions, comprise dominantly iron sulphides and quartz, mostly as veins and vein/breccias. Iron sulphide most commonly comprises pyrite (e.g., Bilimoia, Photo 1), but locally pyrrhotite in hotter

In auriferous quartz lodes the minerals most commonly associated with gold are iron and copper pyrites, zinc blende, galena, and tetradymite. Tellurides of gold are very widely distributed. Other minerals occurring with gold are tourmaline, calcite, uranium ochre, roscoelite, vanadinite, crocoite, wollastonite, gypsum.

A rutilated quartz features the inclusions of Rutile within its crystals. And while we have golden rutilated quartz, the rutile inclusions also be more copper, red-brown, black or silver in color. Most pieces of rutile are small needles such as threads within the stone. The golden rutilated quartz is usually known as the "Hair of Venus".
Deposits consist of native gold and (or) gold-silver telluride minerals in high-grade quartz veins and (or) low-grade, near surface disseminated native gold and pyrite (with or without telluride minerals) in permeable host rocks. Porphyritic alkaline igneous rocks, many of which display explosive-magmatic features (diatremes, breccia pipes,
The company has nine producing mines and digs up silver, gold, zinc, lead and copper. And it has a total reserve base of 550 million ounces of silver and 5.2 million ounces of gold.
After researching gold deposits in Arizona, it is clear to me that Arizona is not only the copper state, but it should also be known as the Copper-Silver-Gold state. Hard to believe, but Arizona has produced much more than 500,000,000 ounces of silver and 16,000,000 ounces of gold along with all of its copper, zinc, lead and turquoise.
reveal that gold, silver, and copper were recovered from this region during the reign of King Solomon (961-922 B.C.). (Below) An air view of the Mahd adh Dhahab gold mine in Saudi Arabia. Swarms of gold-bearing quartz veins (seen as long irregular trenches at a) have been mined for gold and silver for more than 3,000 years.
Awesome honestly thank you guys sooo much. (Sorry for late reply!) This helps me tremendously, It's in a very copper-silver rich area, the quartz even has lots of malachite and azurite running through it. Thank you for noting the relationship between copper colors and gold (especially chalcopyrite) this actually helps me alot.
Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is. Much of the gold mined is actually from ...
1,500 tons of high-grade lead-silver ore were reduced (Gold Hill Standard, 1917). In 1874, the smelter wa s moved to Gold Hill where an additional 500 tons of ore from the Western Utah Copper Company were treated and four carloads of lead-silver bullion were produced. In 1892, the Cane Spring Consolidated Gold Mining

Real gold is very heavy. If you have a piece of quartz with pieces of what you think is gold inside it, try weighing it and compare the weight with a similarly sized piece of quartz. If the quartz with gold pieces in it weighs several grams more than a similarly sized piece of quartz, it's possible that your quartz contains real gold.

Silver as a Native Element Mineral. Silver is rarely found as a native element mineral. When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals.Unlike gold, it is rarely found in significant amounts in placer deposits.

Original methods for the photochemical production of stable copper, silver and gold colloids in the form of films on quartz, and dispersion in liquids were devised. It is shown that photochemical synthesis of colloidal metals is a difficult multiphase process, and includes the formation of low-valence forms of Cu(I), Au(I) and nonmetal clusters, colloidal particles and their agglomerates ...

Evaluation of some epithermal quartz gold-silver systems identified in this manner has led to the discovery of larger gold deposits of other styles (e.g., Porgera, Emperor). Carbonate-base metal gold deposits should be tested for associated epithermal quartz gold-silver mineralisation which has the potential to provide elevated gold grades.
Free gold in quartz veins comes in all sizes, with a full range of gold particles from obvious stuff easily visible to the eye down to gold that can barely be seen with a magnifying glass. The coarser stuff can be found with a metal detector, while the smaller sized gold requires that the rock be crushed and the resulting powder panned.
