Typically, dilute solutions of sodium cyanide (NaCN), normally in the range of 0.01–0.05% cyanide (100–500 parts per million), are used inSodium Cyanide Market for Mining Industry to ,2020-10-30 · Sodium cyanide is extensively used in gold and silver mining. Sodium cyanide is used in mining to extract gold and silver from ores, as these metals have high affinity toward sodium cyanide. Furthermore, low-grade ores and ores of gold and silver that cannot be treated with crushing and gravity separation use the sodium cyanide treatment method to separate gold from other impurities.
