  • Sodium cyanide Formula, Structure, MSDS, Uses and Properties

    Sodium gold cyanide. It is used in mining for extraction of gold and other expensive metals. Gold being a least reactive metal shows a high affinity for cyanide, causing it to oxidize, and dissolve in the presence of oxygen and water. Sodium gold cyanide and sodium hydroxide are the respective products of this extraction process.

  • Calcium Cyanamide lin 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.
