Magnetic separation has been used widely since 1955 for processing a variety of minerals from iron ore in steel production to desulphurization of coal.

Besides, the separation machines are devide into the dry and wet magnetic separation. Generally, iron ore with an iron content of 35% can increase iron content by 20% after magnetic separation. Such a combined process method, the ore utilization rate can reach 90%. In the process of magnetic separation, it saves water, reduces cost and pollution.

Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water

Procedure Of Magnetic Separation Of Iron Ore. 9.4. Typical flow sheets for iron ore separation 9.4.1. Major principles for selection of separation methods. For low-grade iron ore separation it is very important to develop an optimied flow sheet to achieve the best iron concentrate grade and iron recovery while keeping the cost as low as possible.

Magnetic Separation Process Iron Ore. The magnetic roller attracts magnetic ore from the main ore and the waste ore is separated from the magnetic ore Thus we can separate magnetic ore from the nonmagnetic ore Therefore by repeating this process two more times we can get a pure magnetic ore The ore extracting through magnet is done by various steps are …

Iron ore beneficiation technologies which is currently used for processing such iron ores consists of a magnetizing roasting followed by wet grinding and low- intensity magnetic separation Fig. 1. include as final operations several of the following highlow The research reported in this paper addressed the following magnetic field .

Process parameters of magnetic separation Parameter Value Current strength in electromagnet winding, A 1...8 Clearance under the drum, mm 4 Feed rate of the sample, m/sec 0.1 Size of the ore particles, mm â€"0.63 +0.5 The sequence of the separation process corresponded to the method13 and was as follows: the sample of iron ore (60 g) was fed into …

Gravity separation process and strong magnetic separation process are mainly used to separate coarse-grained (2mm-20mm) and medium-grained weakly magnetic iron ore. Among them, coarse and extremely coarse (greater than 20mm) ores are commonly used in heavy medium or jigging gravity separation technology;

Iron Ore Magnetic Separation Process Overview. As we know, iron ore is the important raw material for iron and steel making. There are various kinds of iron ore in the nature, but only several types can be used for iron and steel production, like magnetite, hematite, and …

Present Practice and State of Development. The largest development in the iron-ore industry, using magnetic concentration, is at the plants of Witherbee, Sherman & Co. at Mineville, N. Y., where about 1,200,000 tons of crude ore were mined and separated in 1916. The dry process of separation is used.

Gravity separation process and strong magnetic separation process are mainly used to separate coarse-grained (2mm-20mm) and medium-grained weakly magnetic iron ore. Among them, coarse and extremely coarse (greater than 20mm) ores are commonly used in heavy medium or jigging gravity separation technology ;

Magnetic separation process is the combination of wet and dry magnetic separation methods, which mainly carries out three stages of magnetic ore dressing process.... Know More Weakly magnetic iron ore beneficiation technology
