HYDRAULIC BACKFILL
RHEOLOGY IMPROMENT AND TAILING DENSITY INCREASE
Tailing reuse:
Pilot field projects were carried out in the hydraulic backfill plant, by using ImmoCem. It was possible to increase the pumping of tailings from 55% solid to 65%, maintaining the flow and discharge pressure of the pump at normal conditions.
The use of IMMOCEM reduced the viscosity of the tailings, improving the performance of the pumping system with a higher percentage of solids in the tailings.
