Conclusions
-
1.
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.
-
2.
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.
-
3.
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).
