plant and/or fullscale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.

A conventional cyanidation plant used in processing lode gold ores usually includes crushing, fine grinding, and agitation leaching in cyanide solution. In the heap leachingcarbon adsorptionelectrowinning process, the mined ore, with or without coarse crushing, is piled into heaps on an impervious base (natural bed or artificially prepared pad).
Processing of HighSilver Gold Ores ScienceDirect
This chapter deals principally with ores where the silver grade is sufficiently high to warrant modifiion to the design of the plant relative to that which would be specified if the silver component was not present, and where the silver and gold are amenable to recovery by conventional cyanidation.

Dissolve Gold and Silver with Cyanide
The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc that may be in the ore. In order to leach the
Mineral Processing Operating Cost Estimate of Ore Treatment
Only where a group of mines operates in a single district are costs comparable and then only with reservations. In general, cost systems are fairly uniform, yet in studying costs of a number of plants it is noticeable that in some cases there is a tendency to omit certain operations which are proper charges against ore dressing and treatment.
