Process for improving inline tailings treatment

摘要

Process for improving inline mineral slurries treatment comprising successively:•- providing an in-line flow of slurries (2) in a main stream (1);•- introducing at least one polymer into the main stream through at least one polymer injection point (3) to cause dispersion of the polymer and to start the coagulation and/or the flocculation of slurries (treated slurries);•- splitting the main stream containing treated slurries into two streams respectively :•o a discharge stream (4) which directly transfers a part of treated slurries to the deposit area,•o a split stream (6) which reintroduces the other part of treated slurries into the main stream through at least a reinjection point (7) in a location prior to the at least one polymer injection point.
