An Overview Of Gold Smelting And Refining
Smelting involves melting the gold ore to separate the pure gold from impurities, while refining focuses on purifying the already extracted gold to achieve a higher level of purity. Smelting is typically the initial step in the gold production process, followed by refining to further enhance the quality of the gold.

Using Borax Flux to Refine Gold
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.
