Abstract
A process for improving inline mineral slurries treatment comprises successively: providing an in-line flow of slurries in a main stream; introducing at least one polymer into the main stream through at least one polymer injection point to cause dispersion of the polymer and to start the coagulation and/or the flocculation of slurries to produce treated slurries; and splitting the main stream containing treated slurries into two streams respectively: a discharge stream which directly transfers a part of treated slurries to the deposit area, and a split stream which reintroduces the other part of treated slurries into the main stream through at least a reinjection point in a location prior to the at least one polymer injection point.
