This occurs because of the melting point and the density of the gold as compared with the different melting points and densities of the other metal components of the slag. The gold should slip down into the smelting vessel. After this occurs, you can cool and remove the gold from the smelting vessel and also remove the slag as well.
The gold melting point is 1064.18°C (1947.67°F). This is the melting point of gold if you are melting pure gold but if other metals are present, the temperature will vary according to their individual melting points. 2. How to Melt Gold Flakes? Gold flakes are best to melt in an electric kiln for faster results.

How to Use Iron and Carbon to Refine Gold. Iron is used to remove arsenic, antimony, sulphur. The pot is stirred briskly with an iron rod for a few minutes. Antimonides, arsenides, or sulphides are formed and separate from the metal. Carbon is used to assist iron to melt and to remove oxygen from bullion.
With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
Usually, as the gold travels down a stream, it will tend to avoid as much as possible the curvatures of the rivers. This fact means that particles of gold are more likely to be found on the short side of each curve, not the one that covers the longest distance[13].
