Cyanide is a chemical group consisting of one atom of carbon connected to one atom of nitrogen by three molecular bonds (C≡N) and cyanides are compounds (substances formed by the joining of two or more atoms) that contain a cyanide group (typically shown as CN).
Cyanide produces toxic effects at levels of 0.05 milligrams of cyanide per deciliter of blood (mg/dL) or higher, and deaths have occurred at levels of 0.3 mg/dL and higher (a deciliter equals 100 milliliters).
Cyanide exposure from cassava was linked to poor functioning and later enlargement of the thyroid gland; this is because in the body, cyanide is converted to thiocyanate, which is toxic to the thyroid gland.

 POTASSIUM CYANIDE
Hydrogen cyanide is mainly obtained by the reaction of ammonia with carbon monoxide (Andrussow process) or with natural gas (methane) in the presence of rhodium/platinum catalyst at approximately 1100 C. Very short contact time (milliseconds) is required to obtain the optimum yield and consequently a high operating temperature is required to reach equilibrium.
The principal use of hydrogen cyanide is in the manufacturing of acrylates, synthetic fibers (as a starting material for nylon 66), plastics and cyanide salts, especially sodium cyanide to extract gold from ore. It is used in the manufacturing of organic chemicals; acrylonitrile, metal polishes, dyes, rodenticides, pesticides, synthetic fibers, plastics, and electroplating solutions.
Cyanide salts are utilized in metal cleaning, tempering of steel, gardening, in ore-extracting processes, dyeing, printing and photography, electroplating (gold and silver bath), various organic reactions (Organic cyanide and nitrile synthesis) manufacture of adiponitril for nylon production.
