Gold mining Wikipedia

Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining (ASGM), often clandestine, gold prospecting.

GEOLOGY OF SEDIMENTARY ROCKHOSTED GOLD DEPOSITS

sedimentary rockhosted gold deposits surrounding this fold are the Bannian, Yangyuo, Begao, and Luodong deposits, and the Qingping, Tangxinzhai prospects (appendix I) (Luo, X.H., 1994). Stratabound breccia bodies also are a type of orecontrolling structure or host of sedimentary rockhosted gold deposits in P.R. China. These breccia bodies

Gold Mineral Properties Geology

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties some of which are unique to gold. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.

Geological and geochemical characteristics and formation

The study of geochemistry, stable isotopic compositions, and fluid inclusion characteristics of the Zhaishang gold deposit shows that the oreforming hydrothermal fluid was derived from heated recycling groundwater recharged by meteoric water, rich in organic matter, and possibly mixed with fluid from a deep source being associated with

Geological Characteristics of Rockcontrolling and Ore

On such a basis, the authors analyzed different characteristics of ore belts, deposits, ore veins, geochemical distribution and geophysicalchemical conditions in the Jiaodong gold ore concentration area. It is held that the structures have multilevel orecontrolling characteristics at the oreforming epoch.
