Abstract:
      Flocculating sedimentation test on fine copper oxide ore leached slurry was conducted with composite flocculant. The effects of type and dosage of flocculant, concentration of slurry on sedimentation were investigated. The results show that the sedimentation rate is 5.1 m/h under the optimum conditions including mass concentration of slurry of 8%, dosage of PHP-5 and PHP-8 flocculant of 48 g/t and 12 g/t (dry slag). The test results can fully meet the industrial requirements.
