Filtration of Iron Ore Slime using Synthesized Co-Polymer ...

The present paper reports study on filtration of iron ore slimes using the co-polymer synthesized by grafting polyacrylamide chains on starch backbone. The efficacy of the synthesized polymer was tested for the filtration of iron ore slimes following flocculation. The filtration rate increases with increasing flocculant dosage. However, the improvement is marginal at higher flocculant dosage.

Utilization of Iron Ore Slimes: A Future Prospective ...

In India, iron ores processing industries play a vital role in the Indian economy. During the washing and processing of iron ores, slimes less than 0.15 mm are generated and discarded into the tailing pond. These slimes need processing as they cannot be used directly in blast furnaces. In the present investigation, a typical iron ore slime sample containing 59.22% Fe, 4.76% SiO2, and 4.57% ...
