Gold can be extracted from pyrite by a process called roasting, where the pyrite is heated in the presence of air to oxidize the sulfur and release the contained gold. The gold-containing residue is then treated with cyanide (known as cyanidation) to dissolve the gold and separate it from the rest of the materials.

How do you extract Au from calco-pyrite rock?
You can't extract what ain't there. Why do you think it's called FOOL'S gold? Iron Pyrites = FeS2 = Iron & Sulphur = No gold. Chalcpyrites =Cu2S = Copper & Sulphur ≠ gold.
How do you separate gold in dirt?
To separate gold from dirt, you can use methods such as panning, sluicing, or using a gold pan to extract the gold. These methods rely on the density difference between gold and dirt particles to separate them. It's important to be patient and thorough in the process to ensure all the gold is collected.
