Does melting gold purify it?
The oldest method for purifying gold is to melt it with fire. Gold has a melting point of 1064 degrees Centigrade (about 1,943 degrees Fahrenheit). … With the metal in its liquid form the impurities, or dross, rise to the top and can be skimmed, leaving purer gold behind.
