Mineralogical Investigation of Gold Ores
Mineralogical investigation is a critical and integral aspect of any prefeasibility study as well as one of the quality control measures in the process optimization step (Gasparrini, 1993, Marsden and House, 1993).Mineralogical information must be considered in conjunction with the metallurgical test work program results to ensure that appropriate processing methods are …

How to Identify Gold Ore: Field Tests & Characteristics
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).
