Effect of pulp structurization on the results of magnetic separation in a force field
- 16 Downloads
The results of these investigations indicate the essential possibility and desirability of the use of selective flocculation to intensify magnetic separation in strong and weak fields.
By preparing the pulp by dispersion and selective flocculation before magnetic separation, extraction of iron into the concentrate can be greatly increased without any loss in quality of the latter.
The reagents recommended are caustic soda (1.0 kg/ton), water glass or CSL waste (0.4 or 0.7 kg/ton), and synthetic polymers (7–10 g/ton).
