This is where the gold is separated from the dirt and sand. The cleaned ore is then put into a sluice box, which allows the water to flow through it. The gold particles are then concentrated and washed until they are free of dirt and other impurities. A machine known as a gold pan or cradle is used to sift through the dirt. The brief gold dredging process – normally begins by extracting the ore from the ground. Gold dredging is an excellent choice for those looking to expand their prospecting capabilities with minimal effort. The best approach for a small-time prospector is to find a method that uses as little equipment and manpower as possible. Most are expensive, and the few that are affordable can still be very time-consuming. When it comes to gold mining, there’s no shortage of options available. While this is true for some deposits, others are comprised of other types of metal that contain gold.įor example, gold is commonly mixed with silver and copper. These are typically deposited in shallow bodies of water where they are protected from erosion and are not exposed to the damaging effects of wind and waves.Ī common misconception about gold dredging is that the sediment is composed of pure gold. Most gold is found in sedimentary rocks like shales and sands. Both techniques have their advantages and disadvantages. Gold dredging can be done with equipment that removes the sediment from the water or by hand. It is often used to clean up areas that have been polluted or have an excess of silt or sediment. Although the industry has evolved over the years, the basic process of gold dredging remains largely unchanged.ĭredging involves the process of removing sediment from water and is a very old practice. It is one of the oldest, continuously mined industries in the world, dating back thousands of years. Gold mining is a multi-billion dollar industry.
