"Application of Sodium Cyanide in Gold Mining"

There are many methods used in gold mining. Today, the application of sodium cyanide in it is really important.

Sodium cyanide is strong and toxic. However, in gold mining, it can form a soluble complex with gold, so that gold can be separated from the ore. Leaching the ore in a sodium cyanide solution, the gold gradually dissolves into the liquid, which is the basis of cyanide leaching.

After leaching, another method, such as zinc powder replacement, is used to precipitate the gold from the solution to obtain pure gold. Although sodium cyanide can be used to extract gold efficiently, it is very toxic, so use it with caution. If it is not properly disposed of, sodium cyanide will leak out, which will cause environmental pollution and endanger life.

Therefore, when using sodium cyanide in gold mining, a perfect method must be established to prevent its leakage, so as to ensure ecological safety and complete mining efficiency. Operators should be aware of their risks and abide by regulations, so that sodium cyanide can be used in gold mining to avoid harm.
