It is a white abrasive which is melted at high temperatures. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity.

After reduction for 30 min, the corundum crucible with the reduced pellets were quickly taken out and quenched with water to room temperature . Finally, all the products were collected and manually crushed for magnetic separation, and the magnetic intensity was detected by a telemeter (Bokles, BK-8390, range: 0 ~ 1.999 T).

Direct reduction refers to the process of reducing iron minerals in copper slag to metallic iron particles below the melting temperature of copper slag [].Using direct reduction–magnetic separation technology to recover iron resources in copper slag has fair recovery effect and short reaction time, which is the development trend of …

content. After sintering and magnetic separation, two concentrates with 46% and 32% iron content were obtained from the fine and coarser particle fractions, respectively, and 10% iron recovery were obtained from both of these red muds by direct magnetic separation.13 The reductive sintering– digesting–magnetic separation …

The utility model discloses a production of semi-fragile corundum product is with layering magnetic separation device, including mount table, storage box and feed plate, layering magnetic separation case is installed at the top of mount table, the storage box is installed to one side of layering magnetic separation case, the clearance board is installed at the …

This part of the iron could be dissociated by fine grinding and recovered by magnetic separation. The pure corundum is found in sample 5. Although no iron mineral occurred in the sample, the homogeneous distribution of Fe was observed in the corundum. This part of Fe in corundum occurred as an isomorphism and is difficult to …

Prakash et al. discussed the selective magnetic separation of hematite from quartz and corundum using a magnetic coating method, in which the hematite was coated by the magnetite particles and separated at a magnetic field of 620 kA m − 1 [20].

By multi-step magnetic separation, the magnetic field intensities of the weak and strong magnetic separation stages were 75 and 100 mT, respectively. ...
