Selective flotation of pyrite and gold tellurides

Mar 01, 1997 To overcome the lockup of gold within the roaster, one solution would be to separate the gold tellurides from the roaster feed. Thus, when gold occurs in the form of gold-tellurides with pyrite, which also contains a significant amount of gold, the study of the selective flotation of gold tellurides from pyrite becomes more important.

Jan 28, 2021 Separating Fools Gold from Gold. Here are a few simple tests that almost anyone can use to tell the difference between pyrite and gold. They can usually be done successfully by inexperienced people. However, wise people obtain a couple small pieces of pyrite and a couple small pieces of gold and use them to gain valuable experience.

The slurry is heated at around 65 oC, one more time, it is important to perform tests e.g. 40 to 70oC to evaluate the effect of the temperature on the flotation selectivity between pyrite and arsenopyrite. The separation process could need the addition of a strong xanthate e.g. PAX, 10 to 20 gt and a surface modifier to reactive the floatability of arsenopyrite.

configuration is sequential flotation, where copper bearing minerals are recovered to a saleable copper concentrate, followed by re-activation and flotation of the pyrite which is leached with cyanide to recover gold. Both trains produce a copper concentrate with significant quantities of

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.

On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings rich in arsenopyrite. Arsenopyrite is separated from a...
