Cyanide Recovery - ScienceDirect

01/01/2016  It is often inconvenient, costly or inefficient to recover cyanide directly from gold plant tailings. This is the case if the tailings pulp is difficult to separate into solid and liquid components (as occurs with laterite, high-clay content, slimy or viscous ores) and also if the tailings solids are high acid consumers. In these situations, direct acidification of the tailings results in high operating costs as a result of high acid consumption and inefficient cyanide 01/01/2016  It is often inconvenient, costly or inefficient to recover cyanide directly from gold plant tailings.

CYANIDE RECOVERY COST EFFECTIVENESS IS WHY RECYCLE

To remove cyanide and cyanide-bearing complexes from gold plant solutions, the tailings can either be treated directly, as in the Cyanisorb and SART processes, or they can be processed with an ion exchange resin prior to recovery, as in the Hannah and AuGMENT processes.

Cyanide Recovery SGS South Africa

AVR was the first process used to recover cyanide from gold tailings and, more recently, pulps. The process has been in use for over 50 years. During cyanide use, pH is always carefully controlled and maintained at a high level to avoid the production of highly toxic HCN (hydrocyanic acid gas). During the acidification stage of AVR, the pH level is lowered from approximately 10 to about 4 using sulfuric acid. Then free cyanide and weakly complexed metal cyanide AVR was the first process used to recover cyanide from gold tailings and, more recently, pulps. The process has been in use for over 50 years.
