Magnetic separation process of ores . Introduction Magnetic separation is the process by which magnetically susceptible material is separated from a mixture by the application of a strong magnetic field Iron ores are usually subjected to the magnetic separation process due to the high magnetic susceptibility of iron Magnetic separation was.

A process for recovering both iron and manganese from four manganiferous ores of the cuyuna range was evaluated it comprised 1 low-temperature gaseous reduction to convert nonmagnetic iron minerals to magnetite and manganic minerals to manganeous oxide, 2 acid leaching to extract manganese, and 3 magnetic separation to reclaim iron from ...
Jun 01, 1998nbsp018332the principle of the process consists of converting the iron bearing minerals into the magnetic state so that magnetic separation can be employed to concentrate iron from the ore . the gas used for reduction purposes may be either pure hydrogen, carbon monoxide or industrial gases like blast furnace gas, coke oven gas and producer gas.
In examining the results of separation, we find that the heads compose one-half of the original material by weight, and carry 67 per cent, of iron, or 92.5 of magnetic oxide, equal to 46.3 out of the original 48.3 in the crude ore, while the tails contain the remainder, which is 2 per cent, of magnetic oxide out of the original 48.3 in the crude material but this 2 per cent, is 4 per cent, of the weight of the tails
