sulfides and gold

Besides gold, diamonds, silver, copper, and bronze, which most people know are popular and expensive minerals found in mining, you should also be aware of different elements also in demand in the mining industry. The sulfides and the oxides are two examples, which are consistently mistaken for each other. Here is where they differ:

    The sulfide deposits formed as a result of the first process include mainly pyrrhotites, pyrites, pentlandites, and chalcopyrites. Most others occur because of the latter process. Weathering may act to concentrate dispersed sulfides. Sulfide minerals are the source of various precious metals, most notably gold, silver, and platinum.

    Gold: The mineral native Gold information and pictures

    Gold is usually associated with Pyrite and other sulfides, and sometimes may not be noticed because of the association with these resembling minerals. In certain localities, minerals that contain these sulfides are heated high enough for the sulfides to dissolve, enabling the Gold to remain intact on the matrix. Such Gold is known as "Roasted ...

    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 nonmetallic minerals carry the least gold, and the light-colored minerals generally contain less gold

  • Gold extraction  Wikipedia

    Gold extraction Wikipedia

    Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.

    This is a concern because Arsenic is actually very common in many gold ores. Selenium, mercury and other toxic elements are also found in many high sulfide gold and silver ores as well. To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you dont want to melt them.

    5. Controls of sulfide on gold occurrences. The crystallization or dissolution of silicate minerals has an insignificant effect on the form of Au in granitic magma, because most such gold is generally hosted in sulfides. Au behaves as an incompatible element, and tends to concentrate in residual melts in which sulfur dissociates.

    Sep 04, 2015 · It all depends on your sulfide product - what you have to leach. Leaching works poorly on coarser gold - it just takes forever to dissolve. Some types of sulfides react badly with leach systems, destroying the leach chemicals. If you have significant silver in your ore, many non-cyanide leach systems dont recover silver.
