Iron Ore Recovery From Hematite

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

Iron recovery from refractory limonite ore using

2020-7-10  Actually, limonite is a mineraloid and is mainly composed of iron oxides and hydrous iron oxides. It commonly contains hematite (αFe 2 O 3), goethite (α-FeOOH), ferrihydrite (Fe 2 O 3 nH 2 O), a small amount of lepidocrocite (γ-FeOOH) and feroxyhite (δ-FeOOH). Owing to the unstable chemical composition, high water-content, easy sliming, etc., it is difficult to process the limonite ore by

Processing of Banded Hematite Quartzite Ore for Recovery

2020-1-13  This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31%). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values. Microwave exposure of coarse particles at 540 W for 10 min yielded a concentrate with Fe 56.30% and recovery of 50.68%
