- Ion exchange
resins can potentially be applied in cyanide recycling to
address growing environmental concerns over the use of cyanide
during gold extraction.
- The SXCN Recovery
Process is a safe, environmentally-sound method for removing,
recovering and recycling the cyanide in effluents
from gold and silver leaching processes.
- The recycling of
cyanide using membrane technology, which is currently under
development, is
planned to be applied to the gold metallurgical extraction
process, where the efficacy of cyanide
use is hindered due to the presence of copper.
- Treatment of
cyanide solutions and slurries using air-sparged hydrocyclone
(ASH) technology can reduce the overall cost of cyanide recovery
and re-use.
- Cyanide is also
used in low concentrations as a flotation reagent to aid in the
recovery of base metals, such as lead, copper, and zinc.
- Cyanide in mining
solutions is collected, either to be recycled or destroyed after
the gold is removed.
- CANMET-MMSL has
extensive experience in cyanide recycling technologies as an
economic and ecologic alternative to the destruction methods
currently used by the gold industry.
- Cyanide is a
useful industrial chemical and its key role in the mining
industry is to extract gold.
- Cyanide is used in
mining to extract gold from ores, particularly low-grade ores,
not easily treated through simple processes such as crushing and
gravity separation.
- Safe Cyanide
Recovery process is a safe, environmentally-sound method for
removing, recovering and recycling cyanide in effluents from
gold and silver leaching processes. It is particularly
cost-effective for gold-copper ores.
- Cyanide is removed
and recovered using solvent extraction in a Bateman Pulsed
Column. The solvent is stripped and recovered using a small
amount of caustic solution, and is then returned to the process.
- Cyanide is any
chemical compound that contains the cyano group (C N), which
consists of a carbon atom triple-bonded to a nitrogen atom.
- Currently many
mines would be technologically and/or economically unable to
operate without cyanide.
