Alluvial gold mining means mining from land surface or river or underground. Gold is in a free state in the sediments, and the difference in specific gravity between sand and gravel is obvious. Therefore, placer gold ore beneficiation methods and processes are usually used. Gold is extracted from placer gold mines by gravity separation.
