Zinc precipitation on gold recovery. When cyanide concentration is in excess of the value required, to avoid any significant formation of zinc hydroxide and ensure free cyanide is present to maximize the rate of gold/silver precipitation then excess zinc will dissolve which results in a decreased zinc efficiency.

2016-7-27 ZINC-DUST PRECIPITATION OF GOLD. For many years precipitation by zinc dust, as by the Merrill-Crowe process, has been recognized as the most efficient and economical method of precipitating gold and silver from cyanide solutions. Embodying precipitate filters of the plate-and-frame type, of the vacuum-leaf type, or of the more recently developed pressure bag-filter type, the process is in use in the great majority of cyanide
