The Effects of Cyanide on the Human Body
17.10.2019Cyanide acts on the mitochondria which is the 'power house' of the cells by cutting off the production of ATP (Adenosine Triphosphate) causing cell death. Cyanide affects cellular respiration and disrupts the oxygen utilization. Cyanide combines with iron atom of cytochrome oxidase and prevent the uptake of oxygen for cellular respiration.

DISSOLUTION OF GOLD WITH CYANIDE REPLACING REAGENTS
the production of gold are based on the use of cyanide (Hilson, 2006). In this method a weak sodium cyanide solution (NaCN) of 100-500 ppm is used. Since the Baia Mare disaster in Romania in January 2000, the use of cyanide has been resisted. Germany passed a decree in 2002 prohibiting mines from using cyanide in leaching processes.
