See DetailsAbstract. A comprehensive study of zinc solubility was carried out in de-aerated alkaline cyanide solutions. Parameters investigated were: dissolved oxygen, cyanide and lead nitrate concentrations and pH. Zinc solubility increases significantly with increased dissolved oxygen and cyanide concentrations.Eh-pH diagramshave been developed and used to predict regions of stability of zinc hydroxide, which may inhibitgold precipitation.

Introduction Precious metal recovery from aqueous solution by zinc dust precipitation has been in use since the late 1800s [1]. This technology, originally patented by Salman and Pichard, was applied in 1897 to the Homestake operation in Lead, South Dakota by C.W.Merrill.
