Separating Flotation Gold From Pyrite

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.

What's the best way to seperate Pyrite from gold? Gold

2008-05-16· I use to have a mine in which all of the gold was in pyrite. I would roast the ore using only the heat of a campfire. This drives the sulfur off from the pyrite and turns it into magnetic iron. A magnetic separator would yield a clean pyrite concentrate and I would dissolve the iron with H2SO4. Just A thought.
