Rcovery of gold in pyritic ores Mine Engineer.Com

The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

Fool's Gold and Real Gold How to tell the difference

Non-Destructive Tests. A) Tarnish: Most specimens of pyrite, found in nature, will have at least some tarnish on their surface. Nuggets or small flakes of gold are usually bright and untarnished. B) Color: Pyrite has a brassy color. Gold has a golden to yellow color. Most native gold is alloyed with silver, and if the silver content is high enough, the specimen will have a whitish yellow color.

How to Separate Gold from Pyrite

So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier. Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here

Texture and geochemistry of pyrite from the Gaoche gold

Pyrite is widespread in the Gaoche gold deposit, and can be used for deciphering the complex hydrothermal processes and mechanisms of gold precipitation. In this paper, we carried out elemental and isotopic studies for pyrite from the Gaoche deposit, a newly identified lode-type gold deposit in the northern Wuyi metallogenic belt, to clarify

Pyrite: The mineral pyrite information and pictures

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
