Minerals

Free gold is that which can be easily liberated and is unbound to other minerals Free gold can be rapidly recovered in high amounts using gravity concentration methods Traditionally simply exploiting the high specific gravity of free gold for recovery required little energy and was profit generating. Today however more milling energy is consumed due to the change in mineralogy of gold
