The latter property aids in the beneficiation of magnetite ores. Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but magnetite ores having lower ore grade (generally 20-30% Fe) owing to the presence of impurities. Sino Iron produced and shipped more than 19 million wet metric tonnes of magnetite The presence of appreciable quantity of clay mineral in Indian hematite ore needs an attrition technique using screw scrubber in the beneficiation circuit to remove the ultrafine clays and avoid downstream operational problems.

Introduction: Overview of the global iron ore industry
Turning to iron ore exports and imports, the tonnages are summarized in Table 1.1 for 2012 and 2018 (Australian Department of Industry, Science, Energy and Resources, 2021; US Geological Survey, 2020; United National Conference on Trade and Development (UNCTAD), 2021).As shown in Fig. 1.3, China is the largest iron ore Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial Beneficiation of Iron Ores IspatGuru

Magnetic separation studies for a low grade siliceous iron ore sample
This present paper discusses both the dry and wet magnetic separation techniques used for processing of a low grade siliceous iron ore sample. 2. Materials and methods. About 500 kg of a low grade siliceous iron ore sample was crushed to below 10 mm size by using jaw crusher. The crushed sample was thoroughly mixed and subjected Investigations were carried out, to establish its amenability for physical beneficiation on a low grade siliceous iron ore sample by magnetic separation. Mineralogical studies, with the help of microscope as well as XRD, SEM–EDS revealed that the sample consists of magnetite, hematite and goethite as major opaque oxide minerals where as Mineralogical and Beneficiation Studies of a Low Grade Iron Ore

Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.How to Extract Iron from Hematite: Methods and Plants

Bauxite Beneficiation: An Approach to Value Addition in
The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values. This often requires more complicated processes, such as the use of a high-intensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals.For example, the particle size distribution of iron ore fines is important because green pellets adhere together through capillary and viscous forces from the liquid trapped between solidThe effect of particle size on green pellet properties of iron ore

Developments in the physical separation of iron ore:
As high-grade iron ore resources become less and less due to the rapid increase in steel production, iron ore beneficiation is becoming more and more important. The complexity of new ores also makes the task more and more difficult. Recent advances in magnetic separation are summarized below. 9.5.1. Development of large magnetic Washing of iron ore fines and slime (10% and 25% w/v, slurry concentrations) with two types of surface-active agents (sodium humate (synthesized) and AD 200 (commercial)) at varying concentrations at pH 8 was conducted for ascertaining the efficacy of dispersants in beneficiating the low-grade iron ores.
