Molecular formula:C2CaN2
Molecular Weight:92.11

Calcium cyanide is made commercially from lime, calcium oxide, coke, and nitrogen. The reactions are carried out in an electric furnace. The resulting melt is cooled rapidly to prevent reversion to calcium cyanamide. The product is marketed in the form of flakes, which are dark gray because of the presence of carbon. The extraction or cyanidation of precious-metal ores was the first and is still the largest use for calcium cyanide.
