Gold mining is the extraction of gold from the formation of gold-rich process. There are a
variety of techniques can be mined from the formation of the gold, the most primitive way is
gold, then after Gold Separation Equipment Sieving. Currently on industrial multi-purified gold
cyanide, but cyanide toxic, and therefore are developing new gold extraction reagents.
Gold mining major ways: open pit gold mining can be divided into two and underground mining
to underground mining based. Suitable for open-pit mining in general and micro-fine gold
placer mining. Placer gold mining has two mining and artificial gold mining ship, the former
is used in eluvial zone and the presence of a large number of coarse gravel riverbed areas to
dig for gold richer artificial horizon for the purpose. General dug placer exists only in
some small profitable ore, ore grade of 0.02 g / m3 can be more profitable. Some gold mining
river boat is larger, more stable gold grade gold layer, artificial profits or difficult to
dig a large gold mining company under the gold mining area to the way large-scale mining,
gold mining ship costs are normally up millions of dollars, and therefore requires a good
gold mining operation area. Underground mining is the main way Chinese gold mining, because
most of the Chinese gold deposit is concealed, semi-concealed orebody, requires the use of
open hole ways to mine gold.
In South Africa, the world's most advanced gold mining straight hole to a depth of 3,000
meters. Since gold buried deep underground, sulphide mineral-based gold mining requires a
higher ore grade, simple alternative minimum sulphide ore industry requirements in 2 grams /
ton, mined at an average grade of 4 g / ton to profit . Depending on the complexity of the
gold grade of ore types and optional other associated minerals may be, no useful elements of
high muddy high arsenic sulfide gold ore is required to...
