GOLD RECOVERY FROM CARBON MINTEK

Jul 21, 20160183;32;Carbon fines are produced when carbon, which is used in a carbon in leach (CIL) or carbon in pulp (CIP) process for the recovery of gold, is broken. Typically, these fines, loaded to some extent with gold, exit from a last adsorption stage of the process and are then lost.

The leaching and adsorption behaviour of gold ores

adsorption onto activated carbon, these effects include competing metal cyanide complexes, preg robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it is shown that a variety of metal cyanide species can be used to leach gold from certain refractory ores.

Gravity Gold Recovery, Flotation amp; Carbon in Leach Cyanidation

To further evaluate the process of Gold Recovery by Gravity, Flotation and Carbon in Leach Cyanidation, some cleaner tests with regrind of the bulk rougher concentrate, were conducted. Rougher flotation concentrates were reground to improve leach kinetics. The regrind sizes for these range of tests were not optimized. Regrind discharge sizes of between 24 to 64181;m P80 were obtained.
