At this point, the crude binding matter and the gold metal need to be separated. This is accomplished 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 point.

Gold smelting Flux Lowers Smelting point: If the ore from which gold is to be separated out contains elements and impurities with a high melting point. The process becomes highly energy intensive as high temperatures are required to get the mixture melted down. The addition of flux provides a very desirable solution to this problem.
