What are the treatment methods for cyanide in the waste heap after heap leaching?

1. Natural degradation

Natural degradation can occur in a variety of ways, such as photolysis, oxidation, volatilization, adsorption, and biodegradation. The natural degradation of cyanide in heap leaching occurs continuously, and this destruction can make the waste heap environmentally friendly.

2. Chemical destruction

The fastest way to destroy cyanide is chemical oxidation. Many chemical agents oxidize cyanide. The most commonly used chemical reagents contain oxygen and chlorine. The oxidation reaction can be returned to the reactor after the reaction outside the reactor, or the oxidant can be added to the reactor.

Aluminum alloy die-casting product use
Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, home appliances, and some communications industries. Some high-quality, high-precision, high-toughness, high-quality aluminum alloy products are also used in large-scale aircraft, ships, and other relatively demanding industries . The main use is still in the parts of some instruments.
