The strong solution usually contains from 0.25 to 0.35 per cent, of cyanide and the weak solution from 0.05 to 0.15. A strength of 0.5 per cent, is, however, necessary in the treatment of some ores, and, on the other hand, it is sometimes better to use no solutions stronger than 0.1 per cent, or even more dilute.

At a pH of 11, over 99% of the cyanide remains in solution as CN , while at pH 7, over 99% of the cyanide will exist as HCN. Although HCN is highly soluble in water, its solubility decreases with increased temperature and under highly saline conditions.

Electroplating that uses cyanide in the plating bath which

Electroplating that uses cyanide in the plating bath which

cyanide in the bath works to dissolve the HAP metal added as a cyanide compound (e.g., cadmium cyanide) and creates free cyanide in solution helping to corrode the anode. These tanks are self regulating to a pH of 12 due to the caustic nature of the cyanide bath chemistry. The cyanide in the bath is a major bath constituent and not an additive.
