  • How Do You Identify Silver Ore?

    Silver ore can be identified in the field by evaluating the physical properties of the suspected sample or by submerging it in water. It is also identified by examining the other minerals found around the suspected ore deposit. Examining the physical properties of the suspected silver ore can lead to discerning the true identity of the mineral.
