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

Utilization of low-grade banded hematite jasper ores

Jun 19, 2018· A novel approach for the complete utilization of a low-grade banded hematite jasper ore assaying ~ 47% Fe has been taken in order to address the issue of rapid consumption of high-grade iron ores and the rising concerns of waste disposal. The process includes the enrichment of Fe through reduction roasting followed by magnetic separation, and smelting of the non-magnetic fraction to

Hematite Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C
