The chemical composition of iron ores has an apparent wide range in chemical composition especially for Fe content and associated gangue minerals. Major iron minerals associated with most of the iron ores are hematite goethite limonite and magnetite. The main contaminants in iron ores are SiO2 and Al2O3. The typical silica and alumina bearing minerals present in iron ores are quartz kaolinite gibbsite diaspore and corundum. Of these it is often observed that quartz is the main silica bearing mineral and kaolinite and gibbsite are the two-main alumina bearing minerals.
Magnetic separation is typically used in the beneficiation of high grade iron ores where the dominant iron minerals are ferro and paramagnetic. 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.
Flotation is used to reduce the content of impurities in low-grade iron ores. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica however reverse cationic flotation remains the most popular flotation route used in the iron industry. The use of flotation its limited by the cost of reagents the presence of silica and alumina-rich slimes and the presence of carbonate minerals. Moreover flotation requires waste water treatment and the use of downstream dewatering for dry final applications.
Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale pre-feasibility scale. Significant movement of iron and silicates was observed with examples highlighted in the table below.
The results of this study demonstrated that low-grade iron ore fines can be upgraded by means of STET tribo-electrostatic belt separator. Based on STET experience the product recovery andor grade will significantly improve at pilot scale processing as compared to the bench-scale test device utilized during these iron ore trials.
The STET dry electrostatic separation process offers many advantages over traditional wet processing methods such as magnetics or flotation including

Gold Separation Process In The Mining The process of separation of concentrate mineral ore in a Gold Mining in general should be done in a gradual manner and the function of the separation process is to separate gold ore minerals from mineral impurities or mineral carrier.
The concentration of low-grade magnetic iron ores separating the magnetite crystals from the gangue by the use of magnets is a field of work in which the lessons taught by the development of the porphyry coppers can be studied to advantage. Large-scale operations and the liberal expenditure of enough money at the start to insure the most economical operations are the means of securing the desired results.
In principle low-grade iron ore fines and dolomitic itabirites that are not processable by means of conventional flotation andor magnetic separation could be upgraded by exploiting the differential charging property of their minerals 11.Here we present STET tribo-electrostatic belt separation as a possible beneficiation route to concentrate .
