Beneficiation of a low-grade, hematite-magnetite ore in ...

2014-5-1  In China, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization.

Recovery of magnetite from low grade banded magnetite ...

2018-4-1  There has been a steady increase of iron ore demand in the last few decades. This growing demand could be countered by use of low grade iron ore after beneficiation. Banded iron formations (BIF) are one of the resources of such low grade iron ores. Banded magnetite quartzite (BMQ) is one such BIF and a source of iron phase mineral in the form of magnetite.

The Development of Preconcentration Technology in Low ...

Exhaustion of high-grade magnetite resources and large demand for iron ore in the rapidly developing steel industry promotes the mining enterprises to exploit low-grade magnetite. Low-grade magnetite with a low content of valuable minerals is hard to be separated with the conventional separation process flow because of its high beneficiation costs.

DRY BENEFICIATION OF LOW-GRADE IRON ORE FINES

Magnetic separation is typically used in the beneficiation of high grade iron ores where the dominant iron minerals are ferro and paramagnetic [1,5]. Wet and dry low-intensity magnetic separation (LIMS) techniques are used to process ores with strong magnetic properties such as magnetite while wet high-intensity magnetic separation is used to separate the Fe-bearing minerals with weak magnetic properties such as hematite from gangue minerals. Iron ores such goethite and limonite are commonly found in tailings and does not separate very well by either technique [1,5]. Magnetic methods present challenges in terms of their low capacities and in terms of the requirement for the iron ore

Mineralogy and Geochemistry of A Low Grade Iron Ore

2013-12-24  In total, the Indian iron ores, in general, contain adverse alumina content and require beneficiation to reduce the same in the ore for feeding to the blast furnace. Simple techniques like crushing, scrubbing and washing of iron ores are being adopted to reduce alumina but these techniques have their own inherent limitations and they are not effective to reduce alumina below particular limits. This process limitation along with the demand by the steel plants for low alumina iron ores encouraged researchers to characterize the ores in general and different modes of associations of alumina in particular. In view of this, an attempt has been made to understand the different modes of association of silica and alumina in iron ore
