Treatment for gold ores with high content of carbonaceous matter …
The extraction of gold for the control test without the use of maltodextrin was 12.76% for standard cyanidation and 63.19 % for CIL cyanidation, as for the concentrates obtained using maltodextrin the gold extraction was 70.21% and 87.26 %, respectively. This shows the positive effect of maltodextrin as a depressant for the carbonaceous matter.Web

Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.Web
