Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).

copper-gold ores (higher copper than gold values) the process route is typically flotation and smelting. In the latter case, gold credits are obtained from smelting the copper concentrates and if gold reports to the flotation tailings, they may also require cyanidation which can prove problematic with cyanide soluble copper.

The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth's surface) and endogenetic (formed within the Earth). The best-known of the exogenetic ores is alluvial gold. Alluvial gold refers to gold found in riverbeds, streambeds, and floodplains.It is invariably elemental gold and usually made up of very fine particles.
