Calcium Cyanamidelin-chemical
Sodium cyanide is used in cyanide process in gold mining. It can also be used in the preparation of calcium cyanide and melamine. Through hydrolysis calcium cyanamide produces cyanamide CaCN 2 H 2 O CO 2 → CaCO 3 H 2 NCN. The conversion is conducted on slurries consequently most commercial cyanamide is sold as an aqueous solution.
