Gold processing equipment example. The discharge from the Unit Cell is higher than the feed inlet, thus making it possible to place the Unit Cell in the ball mill-classifier circuit without an elevator or pump. Still another important unit in these cyanide circuits is the "Spiral Rake" Thickener with the beam type, lowhead superstructure.

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

About Gold CIP. Gold CIP is one of the methods of gold extraction by cyanidation. It is a carbon adsorption process of monovalent gold cyanide [KAu (CN)2] after the cyanide leaching of gold-bearing materials. CIP usually applies in flotation gold concentrate, high argillaceous oxidized gold deposit, mercury mixing, and gravity separation tailings.

DetailsCyanide is an expensive reagent, often a major component of gold process operating costs. As an illustration, for a gold ore grading 2.3 g/t, a 1% increase in gold recovery generates incremental revenue of about $1/t-ore at a gold price of $1,300/ oz. For cyanide at a price of $3,600/t delivered to a remote
DetailsAbstract. Cyanidation has been used to extract gold (and silver) from ores, concentrates, and calcines since the 1890s. The precipitation of gold from cyanide solutions by zinc cementation was patented in 1884 and was applied industrially as early as the cyanidation process. Download to read the full chapter text.
