Economic Impact Analysis For the Proposed Cyanide
This standard focuses on the production of sodium cyanide (NaCN) and hydrogen cyanide (HCN). NaCN is a white, cubic crystalline solid. Odorless when dry, it gives off the smell of bitter almonds when damp. It is used in extracting gold and silver from ore, electroplating, case hardening of metals, chelating agents production, hydrocyanic acid production, and dye and
Hydrogen cyanide HCN Manufacturing process for
Hydrogen cyanide (HCN) is an important chemical with over a million tons produced globally each year. The watery liquid or gas is used in a variety of syntheses including the production of adiponitrile (for nylon), methyl methacrylate, sodium cyanide and chelating agents. Most hydrogen cyanide is consumed at its production site, forming other higher-value products.
Hydrogen Cyanide Production Chemical Engineering Page 1
01/10/2014 Hydrogen cyanide (HCN) is a chemical precursor used in the production of several industrially relevant compounds, such as adiponitrile for nylon production, methyl methacrylate for polymer manufacturing, sodium cyanide for gold recovery and for the production of methionine, which is used as a feed additive. HCN is mainly produced though the Andrussow
