How to recover gold from pyrite - Quora
You start with a metric tonne of raw pyrite ore. Crush it into particles smaller than 1 mm in diameter. Have a 1 kg sample analyzed to see it it has ANY gold content. If it does, proceed. Roast it in a rotating kiln at 700 C to decompose the FeS2 (iron pyrite) and remove the sulfur. Separate the iron from the gold (multiple methods possible).
