    Should cyanide still be used in modern-day mining?

    Toxic sodium cyanide has been used in 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 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 of cyanide …

    Extracting Gold | HowStuffWorks

    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

     · Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that has been proven to contain gold or silver and is then separated as a gold cyanide or silver cyanide solution from ground rock. To precipitate residual zinc and silver and gold metals, zinc is added.
