  • Methods of Gold Mining - Geology In

    Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use

  • What is Gold Extraction? (with pictures)

    Jul 03, 2020· Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means. The ore is typically mined first, though this is not always necessary, and then subjected to an extraction method
