Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Placer gold mining was soon joined by hard rock mining, as prospectors followed the gold to its source veins in the mountains. Gold in some upper gravel benches north of the Blue River was recovered by hydraulic mining.

The general focus of this document will be on metaliferrous ores represented by run of mine material described in category 3 above. An exception to the above discussion of mineral processing arises when the valuable component of the ore is extracted directly by chemical methods.
Successful gold mining is generally done in two steps First is sampling or prospecting, and then, production. While some gold bearing creeks and rivers tend to have gold values dispersed throughout their entire streambeds, there is generally not enough gold to make a small scale mining
Tips On Reducing The Impact Of Gold Mining And Processing
The gold mining boom has caused destruction on the Amazon rainforest as artisanal and unlicensed gold miners tear down the environment to access hard to reach gold deposits underneath. These illegal gold miners use mercury to extract gold, leaching the toxic chemical into the air and water.

A bank of 4 Denver Sub A Flotation Cells, 750 Cubic Foot per cell, overflowing the froth product. Flotation is used in gold, mineral processing, copper, coal, to recover fine particles, typically finer than 0.5 mm. Chemical and physical attachment of the solid particle to the bubble, induced by the chemical reagents and conditioners would be a over simplified description of froth flotation.
Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex.It is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold, copper, zinc and silver represents

Processing, smelting and refining gold World Gold Council
The two gold refining methods most commonly employed to derive pure gold are the Miller process and the Wohlwill process. 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.
Mining, process of extracting useful minerals from the surface of the Earth, including the seas.A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic substance, coal, is often discussed as a mineral as well.) Ore is a metalliferous mineral, or an aggregate

Hard rock mining, placer mining, by product mining and gold ore processing are some methods of gold mining. Each method has its unique process of accessing, extracting and processing gold. Hard rock mining is a method that involves the creation of underground tunnels or open pit mines to access gold in a surrounding rock.
Whole of ore CIL extracted between 28 and 79 percent of the gold in feed, with an average of about 61 percent. These results would indicate there is some degree of refractory gold, which would require alternative processing to recover.
