Beneficiation of High-Aluminium-Content Hematite

2010-5-7  In this article, a new process, roasting with addition of soda followed by leaching, is developed to remove aluminium from the ore. Results show that Al 2 O 3 content decreases from 8.16% in raw ore to 2.13% in iron concentrate, and total iron grade increases from 48.92 to 63.21% when the ore is roasted at 1000°C for 15 min with the addition of 14.0% (wt.) sodium carbonate.

Hematite Roasting Beneficiation Process

Phase transformation during roasting process and magnetic beneficiation of oolitic-iron ores. During the roasting process, the P mineral was mainly in the form of Ca 5 (PO 4) while the Hematite decreased with roasting time. No FeO was found before 20 mi.

2017-12-1  The detailed magnetic roasting process was investigated in terms of ratio of reduction area. Reduction area is the area of Mt (Hm would be transformed to Mt during roasting process) estimated by optical microscope. Observation and counting method (see Table 8) were applied for quantifying reduction area. Roasting temperature is 800 °C, and dosage content of reducing agent is 8%.

Mineral dressing (= Orebeneficiation)

2009-5-16  called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the ore minerals and a tailing (discard) containing the bulk of the gangue minerals.

During the roasting process, the mineral phase Fe 2 O 3 changed to Fe 3 O 4, but the original oolitic structure and mineral embedding relation were hardly evolved. This research could enhance our understanding regarding the microscopic view of magnetic phase transformation, and provide help for commercial development of such refractory iron ores.
