The world's gold production has changed over the past 30 years. The exploration and discovery of large, freemilling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, lowgrade deposits or look for smaller, often more complex ones in remote, often hardtoreach locations?
This article focuses on Turkey's gold potential with respect to exploration, development and operation after 1985. Apart from Turkey's geology, which offers a substantial number of volcanicassociated gold (Ag) and goldcopper (AuCu) projects, there are numerous other factors which make the country a favourable place for mining. Turkey has a mining history which goes back...

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7) .
Gold Mining in South Africa Projects IQ Homepage. Making the refining process more thorough and economically viable, South African gold mining projects, such as the ERGO Mines Joint Venture in Brakpan, will facilitate the reprocessing of billion tonnes of gold tailings to refine a further 15 million ounces of gold.
Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.
Artisanal and SmallScale Gold Mining Without Mercury. Mercury is mixed with goldcontaining materials, forming a mercurygold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks. In some jurisdictions,...
One USBM paper summed up five noticeable characteristics of auriferous pyritic ores. The gold occurs as tiny flakes on the crystallographic planes of the pyrite. The gold flakes are very small in size, 510 microns. The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite).
