Three Key Functions of Sodium Cyanide

1. Gold Leaching

Sodium Cyanide selectively dissolves gold and silver without reacting with rock and common impurities, efficiently extracts gold from crushed ore.

2. Stabilize Leaching Solution

Sodium Cyanide maintains alkaline environment, prevents toxic hydrogen cyanide (HCN) gas volatilization and reduces safety hazards.

3. Restrain Impurity Interference

Sodium Cyanide inhibits interference from iron sulfide, copper, lead and other minerals, lowers reagent consumption and raises gold leaching rate.
