Pour the acid-and-bleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments.
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold
Here is a discussion of the procedures to crush Quartz or other minerals and extract the gold from these rich ores. For really large chunks of material, it may be necessary to initially break down the large pieces with hammers. Sometimes heavy-duty chisels can also come in handy in this part of the process as one breaks down large chunks into

Aug 07, 2013· 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.
Nov 09, 2017· Although a variety of treatments to extract gold exist, unless you have loads of money to invest (perhaps something closer to US $100,000) your best bet is to investigate the potential for treating the ore by gravity based methods (gravity methods means the use of gold's high density to separate it from low density materials like quartz).
