  • Method For Treating Suspensions Of Solid Particles In Water Using Post Hydrolyzed Polymers
    Publication number: 20140238943
    Abstract: A method for treating a suspension of mineral particles in water, such as mineral tailings, includes the step of contacting the suspension of mineral particles in water with a specific water-soluble polymer. This polymer is preferably a water-soluble polymer having an anionicity of between 10 to 55 mol %, and more preferably 20 to 50 mol %. Furthermore, this polymer has preferably a molecular weight between 15 and 40 million daltons, and more preferably between 18 and 30 million. The method involves adding the specific polymer into a thickener containing the tailings to treat, and/or during transport of the suspension to a deposition area for dewatering and solidification, or to the tailings to treat followed by a mechanical treatment such as centrifugation, screw press and filtration.

  • PROCESS FOR IMPROVING INLINE TAILINGS TREATMENT
    Publication number: 20120138542
    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.
