What is Potassium Cyanide

Uses for potassium cyanide (KCN) include electroplating, chemical synthesis, and gold mining. KCN is an extremely hazardous substance. It has a bitter almond odor and is a white, crystalline powder that is extremely soluble in water. One of the deadliest poisons known to man, potassium cyanide can kill you within minutes of exposure.

Sulphide (S) ≤ 0.001 %
Na (Sodium) ≤ 1 %


Potassium cyanide’s capacity to prevent cellular respiration is what gives it its poisonous properties. Adenosine triphosphate (ATP), the cell’s energy currency, cannot be produced because cyanide attaches to the iron atoms in cytochrome c oxidase, a crucial enzyme in the mitochondrial electron transport chain. Without ATP, cells are unable to work, and organs quickly shut down, which causes death. Buy potassium cyanide

In the mining sector, potassium cyanide is most frequently used to extract gold and silver from ores. Finely milled ore is combined with a weak cyanide solution in a procedure called cyanide leaching. When combined with the cyanide, the gold and silver in the ore form complex ions that are later separated from the other minerals in the ore by adsorption onto activated carbon or by precipitation with zinc dust. The resulting precipitate of gold and silver is subsequently processed to yield pure metals.
