Effect of Oxygen Enrichment on Sintering Behavior of High Proportion Vanadium–titanium Magnesite Concentrates

To achieve high-efficiency utilization of complex and unmanageable iron-containing minerals, the effects of oxygen enrichment on productivity, yield, flame front speed, exhaust gas peak temperature, and desulphurization reaction of the vanadium–titanium magnetite sintering process as well as sinter tumble index and mineralogy were clarified, with oxygen enrichment concentrations ranging from 21 to 29 vol.
