Ask The Experts How do I recover gold in pyrite? ICMJs

The best answer as to how to recover that gold depends on the amount of pyrite you intend to process. If you have only a few pounds, it can be roasted by heat in the open air and then mixed with a flux like sodium borate and melted with a collector metal like copper. The melt can be poured into a mold and the gold will now be alloyed in the copper.

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).

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

uses of pyrite in gold mining

Some pyrite, according to Geology, can actually contain traces of gold, increasing the price to close to $1,500 per troy ounce if the pyrite contains 0.25 percent gold. This means one ton, which will contain about 73 troy ounces, will be worth more than $109,000.

Pyrite: The Real Story Behind “Fool’s Gold”

Pyrite was once a source of sulfur and sulfuric acid, but today most sulfur is obtained as a byproduct of natural gas and crude oil processing. Today pyrite is sometimes sold as a novelty item or costume jewelry. But pyrite isn’t entirely useless; in fact it’s a good way to find real gold

Difference Between Pyrite and Real Gold

The shape of pyrite nuggets is something that's quite unique and not found with traditional gold. Nearly all pieces of pyrite are formed into the shape of crystals, some of which may have nearly half a dozen pylons coming off the base. Of course this may be hard to see in smaller pieces of pyrite
