Vietti Slurrytec, a leading South African tailings/ore thickening and filtration company, have developed a Process Water Circuit Conditioner (ClariVie44®) for controlling the dispersive properties of ultra-fines within a metallurgical process water circuit (ClariVie44®).
Ultra-fine particles are not captured efficiently by flocculant polymers and often requires coagulation prior to flocculation. Vietti Slurrytec offers an alternative, cost effective strategy to conventional polymer coagulation, which allows for so called "controlled" dispersion of the ultra-fines in the ore.
Since the process water conditioner is not polymer based, it is re-cycled in the process water circuit without the need for continuous dosing. ClariVie44® is dosed into the process water circuit at the required starting dose for the size of the circuit and followed up by regular top-up doses to treat the raw water top-up volume.
ClariVie44® does not contain sodium or chloride ions and is therefore safe for the environment and for plant infrastructure. In addition to providing better water clarity for metallurgical processing, a key benefit is lower operating costs
Certain cost and environmental benefits are realised using this strategy such as:
An example of the ClariVie44® effect on the clarity of flocculated copper tailings slurries are shown below.
