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.

Synthesis of hydroxypropyl guargum-𝑔-polyacrylamide was carried out by ceric ion induced redox polymerization technique at 28 ± 1°C. The graft copolymer was characterized by IR and thermal analysis. The flocculation performance of graft copolymer was tested in 1 wt% coal suspension.
