Flotation of silicates gangue from hematite containing ...

The gravity concentration allows obtaining of iron concentrate from the well-prepared feed (size fraction -53+20 micron) but with very low recovery. Thus, the hematite concentrates with weak silica content and satisfactory iron recovery were obtained by reverse cationic flotation, when it was fed with iron pre-concentrate produced by high gradient

Slag/Metal Separation from H2-Reduced High

ing high-phosphorus oolitic hematite ore was presented mainly for dephosphorization and recovery of iron from this ore. For dephosphorization, it requires not only higher oxygen potential and basicity of slag, but also relatively lower temperature. For recovery of iron, the proper melt-ing temperature and time are necessary conditions for the

Hematite - an overview ScienceDirect Topics

Iron Oxides—Fe 2 O 3. Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains.

On the Recovery of Hematite from an Iron Ore Fine

Electroflotation is a clean technique potentially able to recover fine particles from mineral suspensions. The aim of the present work was to evaluate the electroflotation of fines and ultrafine particles of an itabiritic iron ore using a biosurfactant extracted from Rhodococcus opacus bacteria. Infrared spectroscopy and zeta potential measurements confirmed the interaction between the ...
