The Processing Of Gold Ore To Pure Gold

Raw Gold To Pure Gold Process

The gold in the veins can be in many different forms like nuggets or sheets, or in gold compounds. In recovering gold from vein ore, the ore is first crushed in rod or ball mills. In this process the ore is crushed to a powdery substance from which the gold can be extracted by gravity separation.
