How to Effectively Identify the Gold Ore? | Fote Machinery

Identify gold ore by physical properties. (A)Tarnish: Gold nuggets or small pieces of gold are usually bright and free of stains. If you find some rust on the surface of the ore, it is likely to be pyrite. (B)Color: Most native gold is alloyed with silver, and if the silver content is high enough, the ore will have a whitish-yellow color.
