Abstract
Water soluble polymers are extensively used in industry to achieve solid-liquid separations of particles in colloidal suspensions. In a way to reduce the environmental footprint of the mining exploitation, the oil sands industry is searching for new methods to treat tailings resulting from the extraction processes, by separating the solids and recycling the water. The objective of this work is to improve the flocculation and dewatering efficiency of the water-based tailings through the use of new synthetic polymers. Acrylamide homopolymers of different molecular weights were synthetized to study the effect of molecular weight on flocculation efficiency. Initial ...
