Improved thickener operation at Minera Valle Central

Online interface and turbidity measurement with Turbimax CUS71D and CUS52D

In many cases the measurement of interface in thickeners is done manually, while the turbidity measurement is done by obtaining samples sent to the laboratory. In both cases the solution offered by Endress+Hauser proposes to have the values online.

Customer Challenge

In Mineral processing the thickening stage is very relevant, both concentrate and tailings are needed
with the lowest possible water content, as well as water clarified with the least amount of solids possible. In the case of Minera Valle Central, the challenges are related to get an interface level measurement in the tailing thickeners, to have the crucial parameters in real time, to be able to carry out corrective actions in a timelier manner. And avoid this measurement must be done manually.
