Efficienrly thickener

1. 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 automatethis 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.
