beneficiation or iron ore for blast furnace

This resulted into concentrating the ore from 45.6% - 53.1 % to 76.3%- 82.2%. This gave an ore that could be fed to a blast furnace for extraction of iron. Keywords: Key Words: Ilmenite, Maghemite, beneficiation, iron, magnetic. 1. Introduction . Iron ores occur in deposits of all geological ages. Most of the

    Feb 08, 2020 The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable
