As is well known, cyanide is a kind of highly toxic hazardous chemical, so any mis-operation in transportation, storage, use and other links will cause the events of serious environmental pollution, malignant poisoning, etc.
Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Gold panning is mostly a manual technique of separating gold from other materials.

The geological grade of the ore deposit is relatively high about 50, but the ore body is thinner or has more interlayers. The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade.
