The beneficiation of low-grade iron ores to meet the growing demand for iron and steel is an
important research topic. However, certain ores do not qualify to be treated in physical …

Oolitic iron ore is one of the most important iron resources. This paper reports the recovery of
iron from high phosphorus oolitic iron ore using coal-based reduction and magnetic …

This work illustrates the reduction roasting and magnetic separation studies of a complex
Indian iron ore with 57% Fe that could not be upgraded to> 61% Fe using a flow sheet …

The beneficiation of low-grade iron ores is a key research and development topic in the
mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and …

A low grade iron ore containing 51.6% Fe, 17.6% SiO2, 4.3% Al2O3, and 3.8% LOI was
subjected to reduction roasting followed by low intensity magnetic separation studies. The …

The paper proposes the innovative technology of hydrogen mineral phase transformation–
magnetic separation–acid leaching for iron enrichment and dephosphorization, based on …

Beneficiation of iron ores is an increasingly important topic, as a result of diminishing
reserves of high-grade ores, and the increasing prevalence of mining wetter ores from below …

To reveal the growth behavior and size characterization of iron particles in coal-based
reduction, we reduced oolitic hematite–coal composite briquettes at various temperatures …

Thermal beneficiation refers to the processes where iron ores are pretreated at high
temperatures to achieve desired liberation in subsequent separation. During these …

The present investigation examines the viability of dolochar, a sponge iron industry waste
material, as a reductant in the reduction roasting of iron ore slimes, which are another waste …
