THE CESL GOLD PROCESS

The CESL Gold Process utilizes both methods of cyanide recovery. The major method of cyanide recovery is through the use of AVR technology which has been used elsewhere, though only occasionally. The process as at CESL involves acidification of a portion of the barren stream in a closed vessel to a pH of 2.0 to 2.5.

The Metallurgy of Cyanide Gold Leaching – An Introduction ...

2014-10-20· 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.
