Beneficiation is mostly limited to sie reduction, desliming and classification. The yield is low of about 25-35. During beneficiation, sub grade intermediate products of about 35-40 Cr203 get generated which finds very little or no use and these have been accumulating in the mines. A schematic diagram of a beneficiation.

Representative samples of low-grade aluminous manganese ore was collected from the Maidan quarry of OMDC lease hold from the Bonai-Keonjhar belt. Optical microscopy Leica, DM2500, and XRD Rigaku Ultima IV were used for mineralogical study. Selective elements like Mn, Fe, SiO2 and Al2O3 were analyed by XRF Spectrometry on Philips PW-1400 X-ray spectrometer with scandium and Rhodium targets using Pentaerythritol Al, Si, Thallium Acid Pathalate Na, Mg, Germanium P and Lithium Fluoride LIF, for heavier elements as analying crystals in vacuum medium.

Sink and float studies were carried out in close sied fraction using bromoform as medium specific gravity 2.85. The results are presented in table 2. The results indicate that most of the manganese could be recovered in the sink, so it is possible to reject most of the lighter material by this method. The grade of Mn could not be improved beyond 30 because of the presence of iron minerals.

The result obtained on Moley mineral separator presented in table 3 indicates that no clear separation could be achieved above 75 m sie fraction. Further due to the presence of high iron values in the heavies the grade is reduced, manganese and iron having almost similar densities. A product with 28 Mn having 55 recovery could be obtained at -15075 m sie fraction.

For tabling studies the samples were crushed below 500 m and classified in to -500250 m and -250 m sie fractions and processed through Denver Wilfley table. The results obtained and presented in Table 4 show more or less identical values when compared with that of the mineral separator. A product with 28.4 Mn could be obtained at 33.2 recovery. The quality of the product could not be improved due to the presence of iron bearing minerals.
