    Ore Beneficiation - an overview ScienceDirect Topics

    Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.

    What Is Iron Ore Beneficiation? (with pictures)

    Jan 12, 2021  Iron ore is smelted after going through beneficiation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. High-grade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.
