    • 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.
