Abstract. The inclusion of small amounts of silicon, phosphorus and sulphur in iron ores or concentrates can have a profound effect on the steel making process and thus on the final iron and...

Abstract. In the present work, Natural powder quartz (NPQ) ore was purified based on an integrated approach involving a reductive roasting pretreatment and acid leaching technology. The reductive thermal pretreatment was carried out through roasting in the presence of ammonium sulphate (AS). Compared with the conventional acid leaching ...

Iron removal methods including conventional pre-treatment, magnetic separation, acid leaching, microbiological, roasting, and flotation, as well as combined …

Iron ore slime is the disintegrated part of iron ore generated in a large quantity during mining process and is about 35% of the total iron ore materials [12]. ... The removal efficiency was relatively higher in a basic solution compared to an acidic one because of the electrostatic repulsion of the surface and negatively charged metallic ...

DOI: 10.4236/jmmce.2018.63027 391 J. Minerals and Materials Characterization and Engineering K. Haga et al. Iron ore was established and therefore this study concludes that; 1) Effective removal of impurities from Sanje ore using wet high-intensity magnetic separation requires lower feed pulp density of 2.5% and higher magnetic field intensity ...

Iron ore is known to be slow to dissolve and hard to keep in solution while removing impurities. Our electrochemical process not only accelerates the dissolution of iron ore and keeps iron in solution, but also removes impurities, leaving a pure, clean iron solution for electroplating. This impurity removal process allows Electra to utilize low ...

Enhanced removal of iron from iron-rich manganese ore leaching solution has become a bottleneck limiting the development of the electrolytic manganese industry. Herein, iron-rich electrolytic manganese residue (IREMR) as a seeding to enhance iron removal. The results showed that the iron removal efficiency was 99.97 % with only manganese loss ...

The removal of the ultrafine clay minerals from the iron ore fines helps to make the downstream processes such as grinding, beneficiation, and pelletization easier. Approximately 80–90% of the clay minerals may be discarded by using screw scrubber at the beginning before being fed to the subsequent beneficiation process.

In most cases, arsenic is an unfavorable element in metallurgical processes. The mechanism of arsenic removal was investigated through roasting experiments performed on arsenopyrite-bearing iron ore. Thermodynamic calculation of arsenic recovery was carried out by FactSage 7.0 software (Thermfact/CRCT, Montreal, Canada; …

In this research, an effort is made to separately introduce the various processes, industrial practices, and fundamental research activities to remove sulfur …
