How Can The Value of Gold Change From Mining and Refining?

Gold is brought out of the earth as ore, and the mining process can alter its value. Another way the price of gold can change is during the refining process. These two big variables can make the difference between two seemingly identical pieces of gold. The changes caused by the mining and refining process go even farther than that.Gold refining – Waihi Gold,The gold content is captured in a ‘mud bag’ around the anode. It is washed and dried, then melted and refined in a chlorination process where chlorine gas is introduced into the melting crucible. Gold is separated from the remaining base metals and is poured into granules or bars for commercial sale.
