Current Situation of gold leaching industry Situation of gold leaching industry
Sodium Cyanide
 

Over the past century, 85% of the world's gold has been extracted using sodium cyanide, and sodium cyanide occupies a dominant position in the current gold industry.

Sodium cyanide is a highly toxic chemical with a low lethal dose (0.2g taken by mouth) and rapid action. It is a chemical strictly monitored by the United Nations Chemical Weapons Control Agency. It is also listed as a strictly monitored and managed chemical dangerous goods in China.

Sodium cyanide is often easy to cause safety and environmental pollution incidents during transportation, storage, and use, which poses a serious threat to people's lives and brings huge losses to national property.

As people pay more and more attention to environmental protection, the use of sodium cyanide is becoming more and more restricted. For this reason, countries around the world have carried out a lot of research on non-cyanide and low cyanide directions, and people are constantly looking for alternatives to cyanide gold extraction agents.

Therefore, regardless of environmental protection or mining  environment considerations, environmentally friendly gold extraction will be an inevitable trend in the development of the gold industry.

Sodium Cyanide Accident - Pollution Incident

Cambodia-Violent mining in Black Heart gold mine kills villagers due to excessive cyanide.

A large-scale poisoning incident in the Chetr Borei area of ​​Kratie Province in Cambodia killed at least 13 people and caused more than 300 people to suffer serious illnesses. A survey led by Cambodia’s Minister of Industry Cham Prasidh revealed high levels of cyanide in nearby rivers.

Romania-Gold Mine Cyanide Pollution Incident

On January 30, 2000, a gold mine sewage sedimentation pond in Romania was flooded due to the surge of accumulated water. More than 100,000 liters of sewage containing heavy metals such as cyanide, copper and lead was flushed to the Tisza River, a tributary of the Danube, and downstream. It quickly merged into the Danube River and spread downstream, causing a large number of river fish deaths and the river's water was not drinkable. Hungary and other countries suffered from it, and the national economy and people's lives were dramatically affected to a certain extent.

Experts domestic and abroad have been studying how to replace cyanidation in gold extraction

 

Although more than 100 years of  using  sodium cyanide to extract gold, the world has never stopped researching, developing, and looking for an environmentally friendly gold leaching agent to replace sodium cyanide. Experts and gold manufacturers at home and abroad agree that the use of environmentally friendly gold extraction instead of cyanide gold extraction is the best way to fundamentally solve the potential safety risks of sodium cyanide and the environmental damage caused by sodium cyanide residues in the tailings of gold extraction. The way and the direction are correct, it is very necessary.
