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.
