This is the type recognised by many as typical gold prospecting, where manual panning can be used, although not commercially. Gold which has accumulated as a placer deposit (naturally separated from rock through gravity) is extracted through placer mining which uses water as the loose material is unsuitable for tunnelling. There are four main types of gold mining, varying according to the country of production and their method of extraction – placer mining, hard rock mining, by-product mining and processing of gold ore. Let us take a quick look at the four main types of gold mining methods. Investors often invest in gold mining companies, as a form of paper gold investment.

Gold was mined in different regions, which formed parts of the Roman Empire. Many Roman gold mines have been unearthed today and one has even been found in the UK, in West Wales. These hydraulic mining methods were later used across Europe. The Romans frequently used methods such as hushing and ground sluicing to extract gold from mines that contained loose alluvial deposits. It is now thought that gold mining was popular at the time of the Roman Empire. Historians agree that the world’s oldest known gold mine has been found on an archaeological site in southern Georgia. It is uncertain exactly when human beings started mining gold, but archaeological evidence tells us that it could possibly have been around 4,200 to 4,700 BC.
