What Mineral Is Used Often As Zinc Ore
Tin Ore Mining Process
The tin ore has a higher density than symbiotic minerals, so the mining process of tin ore is usually gravity separation.However, tin ore is often accompanied by iron oxide minerals such as magnetite and hematite, so it is impossible to completely separate the ore only by the gravity separation method.

Zinc
The froth is skimmed off and the resulting zinc sulphide concentrate is dried. This process upgrades the ore, which may contain only 6% zinc, to a concentrate assaying more than 50% zinc. Up to 90% of the zinc in the ore can be recovered. Electrolysis and smelting are the two processes used to produce zinc metal. In Australia, the electrolytic ...
