Sodium cyanide heap leaching gold extraction: what is it, and what harm does it cause?

This will be discussed by a mineral processing technician. In general, sodium cyanide extraction of gold, also known as cyanide leaching, has a long history. Today, almost 30% of the world's gold is processed by this method, which is widely used. The principles of this process can be found at www.dasenming.com.

Advantages: "low cost, good leaching effect

Disadvantages: environmental problems.

A traditional sodium cyanide pool leaching process has long been included in the Elimination Catalogue. At present, most are heap leaching or in-situ leaching of sodium cyanide, but they also fall into the category of gradual elimination, as at this time there is no better technology to replace them.

Due to sodium cyanide's high toxicity, it requires strict management and control before and after use.
