Their concentrate recovery rate was 89.06%, reflecting the effective recycling of hard to process antimony oxide ore. This not only fully uses this valuable resource, but also increases the economic efficiency of such enterprises. A flotation-gravity concentration-reflotation process for antimony oxide ore from Iran was adopted by Chen D.X. [36].

Rotary scrubber. The rotary scrubber is used to clean and screen ore with large mud content but is challenging to wash. The long washing cylinder allows the material to stay inside for a long time, with a vigorous scrubbing ability. The high-pressure washing water washes the inner wall, thoroughly and powerfully dispersing the material completely.
