AI Technical Summary
Existing beryllium ore beneficiation methods suffer from complex processes, environmental unfriendliness, and low beneficiation efficiency. In particular, the flotation process requires strong acid and alkali treatment, which affects environmental safety.
By employing secondary grinding and desliming and tailings removal, combined with a mixed collector of aluminum sulfate, oxidized paraffin soap and modified oleic acid, and by adjusting the pulp pH and froth regulator, beryllium and gangue minerals can be effectively separated, thereby improving flotation efficiency.
It improved the recovery rate and grade of beryllium, achieving a BeO recovery rate of over 75.92% and a grade of over 6.46%, simplified the process flow, and reduced environmental pollution.
