This is much cleaner than the traditional heap leaching using cyanide.

No need for cyanide.

Potassium cyanide is a compound with the formula KCN.

e Each of the devices contained about 100 kilograms of conventional explosives surrounding several layers of chemicals, including potassium cyanide, sodium cyanide, hydrogen peroxide, potassium ferricyanide, nitric acid, mixed acids, as well as various insecticides and pesticides.

While they're not amino acids, we're now finding things like propane and benzene, hydrogen cyanide, and formaldehyde.

The Governments shall promptly inform the Commission of any actual or planned, significantly polluting discharge into transboundary groundwaters or recharge areas, or of other activity with the potential for significant leaching into transboundary groundwaters.

The occupants of a rocket or spaceship having such a propulsion system would be free from all the ill effects of free fall, such as nausea, muscular weakness, reduced sense of taste, or leaching of calcium from their bones.

Smaller amounts of butadiene are used to make the nylon intermediate, adiponitrile, by the addition of a molecule of hydrogen cyanide to each of the double bonds in a process called hydrocyanation developed by DuPont.

Prohibiting cyanide so that the only child of my deceased friend grows up, and who was born after his death, and that he will be threatened while playing or if he touches or inhales this damned material and dies immediately does not console me.
