Starting from a crude ore assaying 45.6% Fe, a fine-grained oolitic iron ore was concentrated by the oil agglomeration technique to 90% Fe recovery and 65% Fe assay. The ore required grinding to minus 5 μm to effect adequate liberation, and the technique yielded optimum results at pH 9. The roles of pH, collector, and bridging liquid concentrations on selectivity and yield of iron …

A novel iron ore agglomeration process using concentrated solar flux, called a solar-based LMP process is proposed. The process has been tested using laboratory experiments inside a hybrid solar simulator reactor setup. The results indicate no change in the reaction mechanism of LMP formation under solar irradiation compared to electrical heating.

ABSTRACT In steel industry and in mines, a significant amount of ultra-fines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting ultra-fines materials. …
