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
Sep 26, 2019 · Answer. If the ore or the gangue can be attracted by the magnetic field, then the ore 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
Four metallic ores (Cassiterite S n O 2 , Pyrolusite M n O 2 , Rutile T i O 2 and Magnetite F e 3 O 4 ) are concentrated by magnetic separation method. It is based on the difference in the magntic properties of the ore components
Dec 26, 2018 · The ores with impurities are attracted by the magnetic field. It can be concentrated by the electromagnetic separation. eg:haematite (iron), copper pyrites, …
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
This method is widely used for the concentration of oxide and carbonate ores. Magnetic separation. The magnetic separation method separates ore from the gangue particles based on the magnetic properties of either ore or matrix. In this method, the ore is finely crushed and passed over the magnetic roller, where one is magnetic, and the other is nonmagnetic
Dec 06, 2019 · Thus, all ores are minerals but all minerals are not oies. Question 4. What type of ores can be concentrated by magnetic separation method? (All India 2011) Answer: Magnetic separation method is used when either the ore or the impurities associated with it are magnetic in nature. Example: Chromite (FeO.Cr 2 O 3) -A an ore of chromium
In case of mineral processing concentration means the ... concentration of an ore. The concentration ... Magnetic separation is a process in ... Get Price; Which Ores Can Be Concentrated By … which ores can be concentrated by magnetic separation. ... separation Iron Ore Beneficiation,Process,Gravity Concentration,Magnetic... Methods of Iron
Sep 04, 2020 · An ore of tin containing FeCrO 4 is concentrated by (a) gravity separation (b) magnetic separation (c) froth floatation (d) leaching. Answer. Answer: (b) magnetic separation
Sep 08, 2020 · Separation process of iron ore. At present, there are about 300 kinds of iron-bearing minerals found in nature. According to their chemical composition, iron ore can be divided into magnetite, hematite, limonite and siderite; The specific magnetic susceptibility of the material is different, and iron ore is divided into strong magnetic and weak magnetic minerals, which also provides a basis for the …
Sep 25, 2020 · For ex: ores of iron such as haemetite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3) and iron pyrites (FeS 2) being magnetic can be separated from non-magnetic silica and other impurities by magnetic separation method. 6.2. What is the significance of leaching in the extraction of aluminium?
It is, also known as gravity separation. Magnetic separation is used when either the ore (or) the impurities in it are magnetic in nature. Ex: Separating iron from its ore hematite Froth flotation separates the gangue particles from the ore, based on the fact that gangue is wetted by water, while mineral is wetted by oil
Apr 02, 2020 · 2) Chromite (FeO.Cr 2 O 3) is magnetic and it can be separated from non-magnetic silicious gangue by this method. This method is also used for the concentration of haematite (Fe 2 O 3 ) or magnetite (Fe 3 O 4 ), pyrolusite (MnO 2 ), ilmenite (ore of titanium), etc
Ores can be concentrated by using any of the four methods - hydraulic washing, magnetic separation, froth flotation and leaching. Crude metal extraction concentrated ore: The concentrated ore must be converted into an oxide, which is more suitable for reduction. The isolation or extraction of a metal from concentrated ore involves two major steps:
How many metallic ores are concentrated by magnetic separation method from the given ores ?
