The application of coal-based reduction in the efficient recovery of iron from refractory iron-bearing resources is comprehensively reviewed. Currently, the development and beneficiation of refractory iron-bearing resources have attracted increasing attention. However, the effect of iron recovery by traditional beneficiation methods is …

WHIM is the short acronym for Wet High Intensity Magnetic Separation. At present, most U.S. iron raw materials are produced from magnetic taconites, which are ground to a nominal minus 270 mesh (53 micrometers), beneficiated by wet low-intensity magnetic separation, and pelletized. The taconite ore bodies generally contain 19 to …

Magnetic separation has long been used to upgrade and beneficiate a wide variety of industrial ... The hard rock deposit for Case Study 2 consisted of iron and titanium bearing minerals as well as vanadium and other gangue minerals. The main goal was to recover the abundant magnetite and ilmenite components; however,

Therefore, here, we consider the use of less costly drum magnetic separators, modernized to work with waste from the dry processing of such ores. Cascaded drum magnetic separators are proposed, which allow to achieve comparable results with [16,17] on the beneficiation of iron-containing ore magnetic separation waste.
