How Much Does Pyrite Cost? | HowMuchIsIt

 · ­Pyrite, the most common sulfide material, comes from a Greek word meaning "a stone which strikes fire." Its metallic luster and brass-yellow color has earned it the moniker you have probably heard before, "fool''s gold. Being used as an ore of iron for centuries, pyrite can be found in some jewelry or as a novelty collector''s item.

How to Separate Gold from Pyrite

 · In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.

Gold in ia

The combined gold and mercury "amalgam" was then separated and heated; the mercury boiled off, leaving the gold behind. However, in ia''s gold-pyrite belt the sulfur-iron pyrite in the bedrock blocked gold crystals from dissolving in the mercury to form an amalgam. As a result, the percentage of gold extracted from the ore was low.
