Abstract

Graft copolymers are being experimented at the laboratory scale as flocculants. All the four graft copolymers, viz. starch-g-polyacrylamide, amylopectin-g-polyacrylamide, sodium alginate-g-polyacylamide and carboxymethyl cellulose-g-polyacrylamide performed well as flocculants on chromite ore fines suspension. Amylopectin-g-polyacrylamide, in particular, performed superior to the rest of the series from the point of view of settling velocity of flocs which is the most important aspect in solid-liquid separation.
