2.2 Mining Methods. Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. ... Magnetic separation methods are mainly used to separate magnetic mineral such as magnetite, in some application hematite, …

So called "Carbonyl Refining Method for Laterite Ore" was developed by INCO up to the full scale pilot stage and included partial reduction of nickel and iron by CO/CO 2 gas mixture and direct extraction of nickel from ore in the form of nickel carbonyl. The product of the refining was forecasted as ferronickel with Fe/Ni ratio of 1.4/1.

with [16,17] on the beneficiation of iron-containing ore magnetic separation waste. 2. Materials and Methods The following material was used for research: iron concentrate from the Bapy mine (Kazakhstan) with 52 percent average iron grade, 2.65 g/cm3 quartzite and tailings— dry process waste of the same mine.

It is noted that the fabricated unit can produce the sinter grade concentrate (63.5% Fe) with a mass recovery of 22.7% from iron ore 1 and 24.9% from iron ore 2. The performance of the fabricated dry processing unit is compared with the wet processing unit.

Stage 4 | Magnetite dehydration. Since the iron concentrate after separation contains some water, dehydration treatment is required. 1 The separated iron concentrate slurry flows into the thickener for sedimentation to remove a large amount of water. 2 After drying and dehydration in a dryer, the dried iron concentrate powder is obtained.

commonly used beneficiation methods for iron ores are the gravity and magnetic separation techniques [4−6]. Gravity separation is widely used in mineral bene-fication practices for its low-cost, ease of operation and easy to control, and eco-friendly nature [4, 7−9]. It is an appropriate method of concentration for size

On the other hand, undissolved manganese and iron in the leaching residues can be further recovered by the roasting and magnetic separation method. This proposed process can recover 0.12–0.25 tons of iron oxalate and 0.33–0.50 tons of manganese concentrate (Mn: 42–55% and Mn/Fe: 2.91–4.5) by processing 1 ton of Fe-Mn ores (Mn: …
