Alluvial Gold Romania is known as a goldrich country one of the richest in Europe distinguished by an area called the Golden Cadrilater in the Apuseni Mountains with two major golden types gold in in situ mineralization and alluvial gold from sedimentary deposits in riverbeds The alluvial gold present in the riverbeds and terraces resulted from the erosion of the rocks over time

Gold Recovery from alluvial deposits is technically simpler than recovering gold from hard rock deposits

Alluvial Gold Deposited by water movement and Eluvial gold disintegration of rock at the site where it originates not there through water movement are essentially primary gold broken down by weathering and erosion and transported by gravity or water movement over many millenia of geological time

Alluvial gold usually takes the form of dust thin flakes or nuggets The first stage in alluvial gold mining is to take the dredged river bed material and separate the small sand faction where the gold is found from the larger mineral fraction In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the mineral fraction

Those three deposits alone have amounted to over 40 Moz of gold in production reserves and resources Spatial analysis of the Nevada state geologic map Stewart and Carlson 1978 indicates 49 percent of Nevada is covered by transported largely unconsolidated alluvial sediments of Neogene to Quaternary age that fill basins between linear
