Extraction of gold found in silt and riverbeds . Gold is found in rough form in some of the stones in rivers and estuaries. This method was used by the gold miner and is still used until now by conducting a manual search of the stone deposits in the bottoms of the watercourses, where gold is likely to be found in large amounts , These deposits are obtained, and then the extraction of gold from them by washing and screening old , Currently, giant machines are used to pull large amounts of sediments in river bottoms and to extract gold from them .
Gold mining by drilling in mines. There are large amounts of gold found in some rock formations, the so-called gold mines, the gold miner breaks the stones in these mines by giant crushing machines, the explosives may be used in this process, then grinding into small parts, Gold through a number of refining operations including melting of stones and obtaining gold in liquid form. The work in these quarries is subject to several considerations, the most important of which is the price of gold in the market and the percentage of gold in the stones.
Extracting gold from the ground . In some places, gold is found underground in large quantities to allow commercial exploitation.
