Mineral processing metallurgy Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other

How Do You Identify Silver Ore? Reference

25.03.2020 · Silver ore is very rarely found isolated in individual nuggets of pure silver. It is much more common for silver ore to be found fused with other minerals such as sulfur, arsenic, antimony or chlorine. Because of this, it is helpful to quickly and efficiently test to see if a rock may have elements of silver ore trapped inside. This is done by heating the rock and submerging it
