Mar 07, 2016 Toxic sodium cyanide has been used in gold mining since 1887, and it remains the primary reagent in use for gold processing today because it allows for efficient extraction of gold from low-grade ore. Since a tailings dam burst at gold mining company Aurul’s Baia Mare mine in Romania in 2000, leaking cyanide into the Somes River and killing large numbers of fish in Hungary and Yugoslavia, the use

Sodium Cyanide Market for Mining Industry to Surpass US$

Oct 30, 2020 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. The gold ore is added to the sodium cyanide solution, which leads to formation of gold molecules. Furthermore, treatment with zinc separates sodium cyanide

How Cyanide Leaching is Used in Gold Mining
