On the Recovery of Hematite from an Iron Ore Fine Fraction

The increase in biosurfactant concentration positively affected the iron recovery and iron grade up to the concentration of 300 mg/L. The iron recovery achieved values of about 80% and 93% for fractions A and B, respectively, whereas the highest iron content was 59% and 64% for fractions A and B, respectively.

Recovery of Iron from Hematite-Rich Diasporic-Type Bauxite

A technique has been proposed for recovering iron from hematite-rich diasporic-type bauxite ore in this study. Direct reduction roasting followed by low intensity wet magnetic separation process was carried out. The parameters including reduction temperature and time, sodium salts, grinding conditions and magnetic field intensity for separation of iron were determined.

Recovery of Iron From Low-Grade Hematite Ore Using Coal

In the present work, iron recovery from a low-grade hematite ore (containing less than 40'% iron), which is not applicable in common methods of ironmaking, was studied. Non-coking coal was used as

On the Recovery of Hematite from an Iron Ore Fine Fraction

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

WO2007071020A1 Process for recovering iron as hematite

A process for recovering iron as hematite from a base metal containing material involves performing a leaching step on the base metal containing material at atmospheric pressure in the absence of an oxidant, using a lixiviant to obtain a solid residue and a leachate containing dissolved iron therein. The lixiviant includes an acid and a chloride.
