Sodium Cyanide Market to hit US$ 3 Bn by 2027

2019-10-22  Almost 90% of global gold production utilizes sodium cyanide. Gold ore, after being crushed into powder, is added to the sodium cyanide solution. This results in the strong bonding of gold molecules to the sodium cyanide. The application of zinc then separates the cyanide from the gold, resulting in the formation of solid gold.

Enhancing the effectiveness of copper and cyanide

2021-6-1  The high content of Na could explain the high acid consumption of this real solution. This latter was a barren solution from a cyanidation plant that treats a concentrate of zinc and gold. This plant includes the use of an INCO process to destruct the cyanide and remove the copper and zinc contained in the barren solution.

Cyanide concentration in the leach tank -

2021-6-16  The free cyanide concentration depends of the size of gold grains in the ore. If there is a little bit of sulphides, it may preg-rob gold if the free cyanide is too low. Determine the effect of free cyanide on the leaching profile and retention time at the lab scale. You may also reduce cyanide

Cyanide Destruction Hypochlorite / Chlorine

2017-3-13  Free cyanide reacts rapidly with hypochlorite (OCl) in aqueous solution to form cyanogen chloride, otherwise known as tear gas. Cyanide also reacts rapidly with free chlorine. However, at high pH, cyanogen chloride is readily hydrolyzed to cyanate and chloride ions. In practice, effective oxidation of cyanide
