摘要

When today’s industrial world is chasing net zero targets, putting the conventional beneficiation techniques to best use in reutilizing the iron ore tailings becomes a buzzword in hand with advanced techniques considering the phenomena of sustainability, energy consumption, capital cost, and limited scalability. Iron ore tailings, a by-product of iron ore processing, pose environmental and economic challenges due to their large volumes and potential toxicities. The chemical composition of the tailings was found to be 44% Fe, 20% SiO2, 9% Al2O3, and 8% LOI. In the present study, two beneficiation routes were adopted. Route A employs carrying out gravity separation followed by reverse iron ore flotation, and Route B employs only reverse iron ore flotation. Based on the results of the tests carried out, the Route A had upgraded the Fe to 57% with 6% SiO2 with a 30% yield along with 95.59% Fe recovery.
