Cyanide
A cyanide is apound that contains the group CN. This group, known as the cyano group, consists of a carbon atom triple bonded to a nitrogen atom.. Inanic cyanides, the cyanide group is present as the anion CN . Salts such as sodium cyanide and potassium cyanide are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that

Chalcopyrite is often associated with pyrite and economical extraction of copper demands selective depression of pyrite from chalcopyrite conventionally sodium cyanide is used as a depressant in alkaline conditions for the selective depression of pyrite from chalcopyrite during the froth flotation process, leading to potentiallyet price.
How does Cyanide Depress Pyrite Mechanisms
First, they show that ferrocyanide, ferricyanide and cyanide or other cyanide species adsorb chemically on pyrite. Secondly, it can be noted that the effects of these three reagents decrease with increasing values of pH, and finally at pH 10.5 and above, the zeta potentials of pyritee solely dependent on the hydroxyl ion concentration. At this stage of the discussion, it will be
Leaching of a gold bearing partially roasted sulphide
Thus, some alternatives to improve gold dissolution can be suggested: a the addition of much more cyanide, i.e., the use of higher concentrated cyanide solutions b to submit the product to some specific treatments that either remove chemical species accounting for degrading cyanide or speeding up their transformation and c use other leaching agents that can be expected to

Cyanide exists in gaseous, liquid, and solid forms. Hydrogen cyanide HCN, also known as prussic acid is a volatile liquid that boils at 25.6° C 78.1° F. Potassium and sodium cyanide salts are water soluble, whereas mercury, copper, gold, and silver cyanide salts are poorly water soluble. Also, a number of cyanidepounds, known as cyanogens, may release cyanide during

Cyanide
Gold can also be associated with arsenopyrite FeAsS, which is similar to iron pyrite fool's gold, wherein half of the sulfur atoms are replaced by arsenic. Gold containing arsenopyrite ores are similarly reactive towardanic cyanide. Cyanide is also used in electroplating, where it stabilizes metal ions in the electrolyte solution prior to their deposition. citation
pyrite Properties Facts Britannica
Nodules of pyrite have been found in prehistoric burial mounds, which suggests their use as a means of producing fire. Wheel lock guns, in which a spring driven serrated wheel rotated against a piece of pyrite, were used before development of the flintlock. Pure pyrite FeS 2 contains 46.67 percent iron and 53.33 percent sulfur by weight.
