Gold recovery systems that use a flow of water over riffles are called "fixed recovery systems." Classification (sizing of material) is the key to fine gold recovery. This is true in both fixed and mechanicaltype recovery systems.
This document provides a general overview of the use of cyanide in the gold and silver recovery process, and is not intended to be a technical reference on the use of cyanide to recover these metals.
Increased Gold Recovery An increase in the dissolved oxygen level of gold bearing slurry enhances the gold cyanidation process. Mines operating at % recovery rates can expect a full percentage increase by boosting dissolved oxygen levels above 20 ppm.
