Concentration of Ores | eMedicalPrep

The process of removal of unwanted material from the ore is known as concentration or dressing or benefaction of ores. It involves several steps. The separation of required material from the ore is dependent on the differences in physical properties of the compound of the metal present and that of the gangue.

Name three ores which are concentrated by froth-floatation ...

The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation.

Which of the following ores cannot be concentrated by ...

For example, iron ores are attracted towards the magnet, hence, nonmagnetic impurities can be separated from them using magnetic separation. Here, Haematite, Magnetite, and Sidderite are iron ores and hence magnetic separation can be used to separate them. Malachite is a Copper ore and hence magnetic separation can't be used to concentrate it.

Characterization and concentration by selective flocculation ...

Based on the characterization studies and selective flocculation/magnetic separation performed with an iron ore slimes sample, it was concluded that 75 % of the particles were below 10 μm and the specific weight was 4.17 g/cm 3. The main identified minerals were: goethite, hematite, quartz and kaolinite.

Concentration of Ores Study Material for IIT JEE | askIITians

This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO 2) 2 being magnetic can be separated from the non-magnetic silicious gangue by magnetic separation.

Notes On Concentration of Ores - ICSE Class 10 Chemistry

These undesired substances are collectively known as gangue (or) matrix. The process of separating gangue from an ore is known as concentration of the ore. It is also called dressing or benefaction. Metals can be concentrated from their ores using any of these methods - hydraulic washing, magnetic separation, froth floatation or leaching.

Metallurgy - Terminology, Types of separation or ...

The denser ore particles settle down in the grooves and lighter gangue particles are washed down by water. (ii) Magnetic separation method . Principle: The magnetic properties of the ores form the basis of separation. When either the ore or the gangue is magnetic, this method is employed. e.g., Tinstone SnO2, the ore of tin.

Concentration of Ores - Self Study Point

The lighter gangue particles are washed away and the heavier ores are left behind. Magnetic Separation: This is based on differences in magnetic properties of the ore components. If either the ore or the gangue (one of these two) is capable of being attracted by a magnetic field, then such separations are carried out (e.g., in case of iron ores).

Magnetic Separation and Iron Ore Beneficiation IspatGuru

Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

Concentration of Ore Definition, Types and Properties of Ore

This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them.

Different Methods Used In Concentration Of Ores

Concentration of Ores eMedicalPrep. The only useful material is ore. Gangue is removed from the mineral for the extraction of the ore. Different procedures for Concentration of Ores Hydraulic Washing. It is based on the difference in gravity of the particles of the gangue and the ore. So, it is considered as a type of gravity separation.

Concentration of ore

Magnetic separation: This method of concentration can be applied when the gangue and the ore particles have different magnetic properties. For example, if the ore particles are magnetic in nature and if the gangue particles are non magnetic, then a strong magnet can be brought and the magnetic ore particles can be sucked out from the powdered ore.
