Abstract
A description of the agitation leach plant
used for treating gold
-
copper ores
a
t
Anglo Asian Mining’s
Gedabek
mine in Azerbaijan
is given.
The plant employs
a unique resin
-
in
-
pulp system for gold recovery.
The integration of the agitation
leach plant into the existing heap leach/ADR/SART operation is described.
Operational problem
s caused by increasing amounts of copper in the Gedabek
gold ores are outlined.
Previous work on the use of ammonia in copper
-
gold
cyanide leach systems is reviewed.
T
he test
work
leading to the
introduction of
ammonia in the industrial leaching plant is
described. In the plant it was found
that the extraction of copper was halved
by the use of ammonia
, thus leading to
significant reductions in the amount of cyanide consumed in the full
-
scale
leaching system.
