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. Randy in Gunnison

Pyrite Processing Plant. Ore information: The mineral ores contain 35.68% sulfur, 29.24% iron, and 3.65g/t gold, with a high extraction value. According to phase analysis, the gold in the ore mainly exists as gold sulfide, gold oxide, and gold silicate. We must destroy the pyrite crystal structure in the sample to fully expose the gold mineral before we can recover the gold.
