Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called ''hydraulic mining'') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer

Gold was one of the first precious metals mined because it commonly appears in the ground in its natural form. Ancient civilizations such as the ancient Egyptians used gold to decorate their tombs and temples, and gold artifacts dating back more than 5,000 years have been found in
Alacer Gold Corp. is a leading intermediate gold mining company, with an 80% interest in the worldclass Çöpler Gold Mine in Turkey.
Gold was produced in the southern Appalachian region as early as 1792 and perhaps as early as 1775 in southern California. The discovery of gold at Sutter''s Mill in California sparked the gold rush of 184950, and hundreds of mining camps sprang to life as new deposits were discovered. Gold production increased rapidly.
· Akyem is an openpit gold mine located in Birim North District in the Eastern region of Ghana, the seventh biggest gold producing country in the world. The mine is whollyowned and operated by Newmont Mining Corporation, and commenced production in October 2013. It is Newmont''s second mining
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold

Gold mining in Colorado, a state of the United States, has been an industry since also played a key role in the establishment of the state of Colorado.. Explorer Zebulon Pike heard a report of gold in South Park, presentday Park County, Colorado, in 1807.. Gold discoveries in Colorado began around Denver; prospectors traced the placer gold to its source in the mountains west of Denver
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis.
