separation of pyrites from gold

WO1993010904A1   Flotation separation of arsenopyrite from

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO3 ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings

Five Common Gold Separation Methods You Have to Know

Gold vs. Pyrite. The Difference Between Gold and Iron Pyrite

Proper gold panning will easily separate the two, as the small specks of pyrite will wash out of the pan while the denser gold particles will be retained. The color is also a good indicator between the two. While gold obviously has a golden color, pyrite generally has a brassy and shiny coloration.

Commonly called fools gold, pyrite is the Earths most abundant sulfide mineral. Recognized for its brass yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. As flotation also can be used for pyrite ore separation, though flotation separation has deficiency

Pyrite Mineral  Uses and Properties

Some pyrites can contain 0.25 gold by weight or more. Although this is a tiny fraction of the ore, the value of gold is so high that the pyrite might be a worthwhile mining target. If pyrite contains 0.25 gold and the gold price is $1500 per troy ounce, then one ton of pyrite will contain about 73 troy ounces of gold worth over $109,000.

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 thises under the head of non amalgamable gold
