Removal of zinc cyanide from a leach solution by an

2000610&ensp·&enspIn this study an anionic ionexchange resin, Lewatit MP62, was used for the treatment of excess zinc cyanide from alkaline leach solutions. Ionexchange tests were conducted in a laboratoryscale glass column using recycled water from the 100th Year Silver Cyanidation Plant in Turkey. It contains 474 mg/l Zn and 720 mg/l CN.

cyanidation plant for zinc in colombia

Dissolved zinc cyanide complex is built up in the cyanidation plant reaching levels that require a bleed from cyanide solutions . In this context, the SART process applied to recover cyanide and zinc could be implemented in cyanidation plants such as Cerro Vanguardia [ 13 ], La Coipa [ 14 ], El Pe241243n, and Yanacocha, among others [ 15 ].

3 Commonly Used Zinc Powder Feeders In

Zinc powder acts as a reducing agent in the zinc powder replacement process in the cyanidation plant. The uniform and reasonable feeding of zinc powder can not only reduce the content of residual zinc, but also reduce production costs and improve the replacement effect.

Zinc Cementation ScienceDirect

201611&ensp·&enspAlthough zinc is typically added dry, some operations premix it with a cyanide solution. This can return any zinc oxides and hydroxides present back to the metallic state. A bleed from solutions circulating in a MerrillCrowe plant is often required to control the buildup of zinc, iron, and other basemetal cyanide concentrations.
