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.

In comparison, fine gold, as well as gold flour and dust, can fit through small openings, such as the ones of a 40-mesh screen. These can be as small as 0.4mm (0.01in) . The tiny size of such particles makes their recovery much more challenging than what you would experience while prospecting for nuggets.
