Mining : What Is Gold Mining? Engineering geology
Gold is also produced through mining, where it is not the main product. Large copper mines, such as the Bingham Canyon mine in Utah, often recover together with copper considerable amounts of gold and other metals. Some sand and gravel pits, such as those around Denver, Colorado, in their washing operations may recover small amounts of gold.

Gold mining is the process of mining of gold or gold ores from the ground. There are several techniques and processes by which gold may be extracted from the earth.
Geology & Mining
A relatively untapped industry with huge potential at the local level of businesses is small scale mining, with approximately 95,000 ounces of gold exported in 2012. Between 60,000 and 80,000 small scale miners, earn a living out of alluvial mining by commonly using non-mechanical methods thereby making a contribution to Papua New Guinea’s total production of 1.9 million ounces of gold in 2012.

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
Gold mining Wikipedia
Gold mining can significantly alter the natural environment. For example, gold mining activities in tropical forests are increasingly causing deforestation along rivers and in remote areas rich in biodiversity. Other gold mining impacts, particularly in aquatic systems with residual cyanide or mercury (used in the recovery of gold from ore), can be highly toxic to people and wildlife even at

Under the Eastern Roman Empire Emperor Justinian's rule, gold was mined in the Balkans, Anatolia, Armenia, Egypt, and Nubia. In the area of the Kolar Gold Fields in Bangarpet Taluk, Kolar District of Karnataka state, India, gold was first mined prior to the 2nd and 3rd century AD by digging small pits.

The rush of 400 miners soon exhausted the shallow alluvial and eluvial gold on the island, so the Bristish Administrator, William MacGregor (later Sir William), used HMS Swinger to take miners prospecting on nearby islands, eventually finding gold on Misima in October 1888. By 1895, gold had also been identified on Woodlark Island.

The gold mineralization intersected in 2014 drilling is hosted by at least two generations of mineralized veins. The earliest veins trend east-west, and dips are seldom more than 40 degrees. These veins have southerly dips in the west Edna area. The younger veins, such as the Custer vein, are high angle and cut the earlier veining.
