Analysis of the gold recovery profile through a

Leaching in the grinding circuit is currently practiced in plants that process gold ores with low content of cyanide consuming minerals. The high gold recovery observed in the grinding–classifiion section of the plant is commonly explained by the inherent high initial dissolution rate of gold observed in gold ore cyanidation, or by the intense agitation prevailing in grinding mills.

Find the sweet spot Optimise the grinding circuit

Background: SAG Mills and Ball Mills are the work horses of most mineral processing plants. Their purpose is to reduce the ore to a size that allows separation of the valuable minerals (e.g. gold) from the waste rock. The yield/recovery of gold from downstream processing stages improves if the solids are ground finer in the grinding circuit.
