Learn MoreThe circuit incorporates crushing and coarse grinding to 200µm, then gravity recovery, possibly in combination with flotation followed by intensive cyanidation of the gold concentrate. The tailings from the gravity and flotation treatment are then stored in a tailings facility separate from the gravity/flotation concentrate. Therefore
Learn MoreGravity Recovery Gravity recovery averaged % of the feed gold to the processing plant for the 9 month period Jul-09 to Mar-10. Gravity recoverable gold (GRG) testwork on the ore sources being treated indicated that higher gravity recovery should have be achieved through the processing plant. The predicted gravity recovery
Learn MorePlant experience indicates that higher gold production can be obtained by placing the enhanced gravity concentrators on cyclone feed. Speculation on the reason for the improvement includes: Treating the lower pulp density found in cyclone feed streams results in a stage recovery improvement sufficient to overcome the slight reduction in feed grade. The following table
