hematite ores and requires beneficiation

Ore Beneficiation - an overview ScienceDirect Topics

Hematite and magnetite are the most prominent iron ores. 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.

COLUMN FLOTATION FOR THE BENEFICIATION OF IRON

2020-5-6  India is bestowed with rich iron ore reserves in the form of hematite and magnetite. Most of the iron ore mines produce hematite ores and have washing plants to produce lumps as well as fines. During the washing process, around 8-10 million tons of slimes containing around 48-60% of Fe are discarded every year.
