Gold Smelting Process Sciencing

The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This isplished by pulverizing or crushing the gold ore, and then placing it in a furnace. The furnace must reach temperatures in excess of 1064 degrees Celsius, in order to elevate the gold above its melting
