Gold in Arsenopyrite. As case study for the processing of an ore with a refractory component of visible and invisible Gold associated in and with Arsenopyrite had a gold content in the feed ranged from about 1.0 g/tonne to about 8.7 g/tonne depending on lithology. There was some difficulty in measuring the feed gold content due to the presence ...
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well ...
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. Get More
1. The Characteristics of Gold-Pyrite Ore. When determining the beneficiation process of gold-pyrite ore, it is necessary to understand the material composition of the ore and the symbiotic relationship of gold in the pyrite. In general, the mineral types of this ore are simple and the content of pyrite is high.
This process was responsible for a number of physical-chemical changes in the liquid, all of which contributed to the formation of the As- and Au-rich overgrowths in pyrite: (1) removal of H2O ...

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).

Process mineralogical techniques can provide useful information on the mineralogy and textures shown by pyrite and arsenopyrite particles that have been roasted to enhance extraction of gold from refractory gold ores. Dark-field reflected-light microscopy has been found to especially reveal the extent of development of porosity and permeability in the roasted particles. X-ray diffraction has ...
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.
In general, gold-pyrite or gold-copper minerals associations have no problems and gold can be recovered without major problem. The lack of good liberation is a problem and the comminution circuit is the key element. The treatment of auriferous pyrite or silver sulphosalts with gold, have an excellent recovery by flotation.
