´╗┐Improving the efficiency of the tailings thickener in a gold flotation plant
A customer had a multiple gold mines, that were processed through the flotation plants. many of these gold mines had different settling characteristics, these characteristics affected tailings thickener with high efficiency and the instrument that tested settling rates in the incoming that feed well failed from time to time. It meant that the suspended solids increased and the thickener rate changed, decreasing the quality of the return water back to the prep plant. Hawk Measurement Systems solved the problem by providing a high powered three-crystal sonar transducer with automatic scum cleaning impact plate.

The two outputs of the sonar system supposing: the one outputs is low density interface (used Hindered/fluffy layer ),and the other is Heavy compacted density interface (used BED Level) of the sonar system.

The high powered three-crystal array transducer, which is penetrated the suspended solids, even under poor settling conditions. this low density interface could also be used, in the thickener dosing control loop to automate this function if the instrument test failed.

This Heavy compacted density interface was used as one of the input loops.To control the underflow pump, this output is guaranteeing an optimised density which is pumped to the tailings dam. As the deviation moved greater than a set distance flocculent would increased. As the deviation decreased flocculent would decreased. The hindered/fluffy layer was used to monitor the deviation distance between the hindered/fluffy layer and the heavier compact bed.

Xinhai thickener equipments claims to manufacture the largest range of sonar transducers to provide optimised performance, for all bed level thickener applications e.g high efficiency thickener etc.
