In the mineral processing industry, dry magnetic separation is commonly used for removing tramp metals [10] and the coarse cobbing of magnetite ores [11,12]. However, it is ine cient for processing finely ground magnetite ores [7,10]. This is because conventional dry magnetic separators are e ective

Coarse Magnetic Separation Of Magnetite Ores. Figure 9.2 shows a permanent magnetic drum separator which consists mainly of a permanent magnet system a rotating drum a separating chute a feed tank and a flushing pipe. For magnetite separation the magnetic field intensity on the surface of the drum is between 0.1 and 0.4 T. However for other applications

Processing Of Magnetite Iron Ores Comparing Grinding. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation the separation step between grinding stages progressively reduces the amount of material to be ground.

20/04/2017· 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

As a result of dry magnetic separation at about 750 Gauss magnetic field conducted with -0.212+0.106 mm size fraction under optimum conditions, a magnetite concentrate assaying 54.41% Fe was,

Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation. The separation step between grinding

of magnetite ores using low-intensity magnetic separation. Although magnetite stoichiometrically contains the highest iron (72.4 wt %) compared with all the other sources of iron, its low-grade ore state usually contains low iron—magnetite ores located in Australia usually contain iron grades between 14 and 45 wt % [4–6]. These ores are of low economic value in
