Flocculation of chromite ore fines suspension using polysaccharide based graft copolymers
N C Karmakar B S Sastry R P Singh
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.

Grafted hydroxypropyl guargum: Development, characterization and application as flocculating agent
B R Nayak D R Biswal N C Karmakar R P Singh
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.
