Another simple test: Crush the sample into quartz sand with a mortar & pestle, then use a gold pan to separate the material by specific gravity. Gold metal should be heavy enough that it won''t move when sand and water are gently swirled around the bottom of the pan.

You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.

processing gold from the quartz
This gold processing method is suitable for gold-bearing quartz veins with misproportion dissemination and low-sulfur. Since the monomer-separated gold is recovered in a timely and early manner in the grinding circuit, the total recovery of gold can be increased. This gold extraction process is a widely used process in China''s gold processing plant, in which the gold recycling rate of gravity

This is an alternate method to using AquaRegia. The problem with using acids like this with "gold ore" is that other metals are almost always present in the ore with the gold, so once you dissolve the gold into solution, other metals are also spoiling the mix, which makes removing the gold even harder to do. Sulfuric Acid will "not" dissolve gold.

The crude gold is melted and then treated with chloride. This converts any foreign elements or minerals still in the gold into chloride, which will then naturally drift off the gold. The result of this process is 99.5 percent pure gold. The final step is to cast the gold into electrodes or anodes and place them in an electrolytic cell.
