Acrylamide diallyl dimethyl ammonium chloride copolymers as improved dewatering acids for mineral processing

摘要

An improved method of dewatering mineral slurries which comprises treating said slurries with a dewatering amount of a copolymer of acrylamide and DADMAC, which polymers are characterized as containing from 3-50 mole percent of acrylamide and having a Reduced Specific Viscosity of at least 2.
