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.
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
MIN#GOLD5 NEW!. Exceptional specimen featuring a brilliant leaf of Native Gold rising up from bright white Quartz matrix! This very rare locality piece is a characteristic style found twice In the 1880s and later in one pocket in the early 1990s.
Gold is one of the first minerals used by prehistoric cultures. The Latin name for this mineral was quot;aurumquot; and J#246;ns Jakob Berzelius used Au to represent the element when he established the current system of chemical symbols. The Old English word quot;goldquot; first appeared in written form about 725 and may further have been derived from quot;gehlquot; or

Gold is the most malleable and ductile metal, which makes it very easy to work never tarnishes, and is unaffected by most chemicals. However, it can discolor by exposure to chlorine, bleach, and certain detergents. Pure Gold lacks resistance to pressure and easily bends.
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. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.
Gold: The mineral native Gold information and pictures. Gold is one of the heaviest minerals. When pure, it has a specific gravity of Due to its weight, it can be panned because the Gold sinks to the Rock.

Gold In Minerals And The Composition Of Native Gold. Gold in minerals and the composition of native 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 nonmetallic minerals carry the least gold and the light colored minerals generally contain less gold than the dark
#0183;#32;Pure elemental gold is 24 karats, while 18karat gold is 75 percent pure gold, 14karat gold is percent pure gold, and 10karat gold is percent pure gold. The remaining portion of the metal usually used in gold jewelry and other items is silver, but items can also consist of other metals or a combination of metals, such as platinum, copper, palladium, zinc, nickel, iron, and cadmium.
A native metal is any metal that is found in its metallic form, either pure or as an alloy, in nature, The iconic image of gold mining for many is gold panning, which is a method of separating flakes of pure gold from river, It is sometimes found alloyed with silver and/or other metals but true gold compound minerals are uncommon, mainly a handful of, Further information: Copper mining in
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.
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are goldbearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.

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
Thank you also for me, this means that to exploit the gold in heavy sediments it is necessary to crush them in more little part, hoping to free the gold contained in to the host mineral.
