Advantages of Using Sodium Cyanide in Gold Mining

1.Excellent Selectivity and High Gold Recovery Rate

Cyanide ions form highly stable soluble gold complex with elemental gold under ambient temperature and pressure,

effectively dissolving fine-grained and encapsulated gold particles.

Gold recovery of oxidized ores reaches 90%–98%. Even low-grade heap-leach ores maintain stable recovery above 85%,

a performance hard to match by most non-cyanide substitutes.

2. Abundant Supply and Low Production Cost

Sodium cyanide is mass-produced industrially with stable supply and low unit price.

Cyanide leaching achieves extremely high efficiency in extracting gold from ores. In most cases, the gold recovery rate can exceed 90%.

Such superior efficiency allows more gold to be recovered from mineral ores, which substantially improves the profitability of mining operations.

3.Broad Compatibility with Nearly All Gold Ores

It is applicable to oxidized ores, semi-oxidized ores, low-grade lean ores and so on. 

Flexible processing scale: Suitable for small stirred-tank concentrators as well as

large-scale open-pit heap leaching operations of millions of tons, compatible with mines of all sizes.
