Description

Sodium cyanide is a vital basic chemical raw material widely used across various industries. It plays a critical role in:

Basic chemical synthesis
Electroplating and metal surface treatment
Organic synthesis (pharmaceuticals and pesticides)
Metallurgy, especially the refining and plating of precious metals such as gold and silver

Application in Gold Ore Dressing

Sodium cyanide is extensively used in the metallurgical industry, particularly in the extraction of gold and silver from ores. It serves as a complexing agent, enabling the dissolution of gold and silver into solution, which can then be recovered through various refining methods.

In gold ore beneficiation, sodium cyanide is used in processes such as:

Carbon pulp (CIP)
Heap leaching
Carbon-in-leach (CIL)

These methods rely on cyanide’s ability to form strong complexes with gold, significantly enhancing gold recovery rates and improving the efficiency of the extraction process.

Note: Sodium cyanide is a highly regulated chemical. Please ensure you have the necessary import permits before procurement.
