Read MoreJun 16, 2017 Grinding circuit efficiency is pivotal to the performance of ore beneficiation. However, establishing stable operating conditions to maximize throughput, energy efficiency and ensure optimal particle size is a challenging task for any grinding circuit. Variable feed ore characteristics and circulating loads with sometimes complex circuits.Development of large re-circulating loads. Control of the re-circulating loads is particularly important in the coarse and regrind circuits. The coarse rougher concentrate is devoid of fines and does not float well in the cleaners. In order to maintain acceptable recoveries in the coarse cleaning circuit the regrind second cleaner concentrate.

The retention of GRG within the grinding circuit allows for effective gravity recovery of gold from within the grinding circuit.The FloatStar Flow Optimiser controls circulating loads and mass pull in the flotation circuit. It is well known that circuit performance (grade and recovery) is strongly affected by these parameters. By stabilising circulating load and mass pull, it is possible to ensure consistent circuit performance.
