Magnetic Separation of Phosphorus Enriched Phase from

This slag was grinded in iron mortar to 3 classes of particle size: 32mm, 53mm, and coarse (10–300mm), to be used in a magnetic separation experiment. 2.3. Magnetic Separation Experiment A schematic diagram of the apparatus used in the mag-netic separation experiment is shown in Fig. 3. 0.14g crashed slag was added in a Pyrex cell (f16.5mm

High-Titanium Slag Preparation Process by

Wet grinding and magnetic separation were used for beneficiation of the reduced sample for efficiently separating the slag iron and preventing the formation of agglomerates between slag and metal. For the sample with a carbon dosage of 13 pct, Na2CO3 dosage of 8 pct, reduction temperature of 1673 K (1400 °C), and 90 minutes holding time, high
