An iron ore sintering process is the first procedure of steel-making industry. It produces sinter for feeding into the blast furnace (BF). Empirical experiences show that a 1% decrease of iron grade (TFe) in produced sinter turns into a 2% increase of BF fuel ratio and a 3% decrease of BF output (Wang, 2011).Web

Flotation is a solid-liquid separation driven by the wettability of minerals–that is, whether they attract water (hydrophilic) or repel water (hydrophobic). During this process, bubbles are injected into the pulp (the free-flowing mixture of water and powdered ore). As the bubbles rise through the pulp, the hydrophobic mineral particles ...Web
