Aug 05, 2018· Gold is very heavy! Pyrite is not. The specific density of pyrite is 5 and the specific density of gold is over 19! That means that the same volume of gold weighs 3.8 times that of pyrite. All methods of gold mining use this fact to separate gold from lighter materials, including pyrite.

The invention relates to the technical field of wet metallurgy and in particular relates to a method for extracting gold from pyrite. The method for extracting gold from pyrite is characterized in that the pyrite is pretreated so that gold in the pyrite is exposed from the crystal lattices of the pyrite, and therefore, the gold is capable of certainly reacting with hydrochloric acid and

Pyrite is an iron sulfide with the chemical formula FeS 2 (iron (II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite is sometimes called Fools Gold because of its similarity in color and shape to Gold. In the old mining days, Pyrite was sometimes mistaken for Gold, as they frequently occur together.

Oct 28, 2016· In general, pyrites yields only a small proportion of its gold contents if it is run over the amalgamated plates, and if it is ground very fine in a pan with mercury the percentage extraction is better. Among the old processes used for the amalgamation of the gold in pyrites may be mentioned the treatment in revolving wooden barrels with mercury, as practised at the St. John del Hey Mine, and

Jun 29, 2021· We looked into an extraction process called selective leaching, using a fluid to selectively dissolve the gold from the pyrite. Not only do the dislocations trap the gold, but they also behave as fluid pathways that enable the gold to be leached without affecting the entire pyrite. Implications for gold production

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

It is not easy to get the gold out of that pyritethere is no simple and easy method. 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.
