Methods of mining iron ore

This saves mining operations multiple millions in USD every month since iron ore beneficiation increases significantly the costs per ton of ore. Control of the moisture content on the mining conveyor belt (NIR) together with accurate monitoring of the composition of iron ore before shipment guaranties constant ore quality to avoids penalties

    Feb 14, 2019 Extraction. Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines
