Paper Title:
Study of Strengthen Flotation Separation for Middle-Low Grade Bauxite
  Abstract

The ore properties and strengthen separation of bauxite were studied in this paper. The parameters in strengthen separation, such as dosage of collectors, flotation turbulence and inflation etc., were also discussed. With the increase of collector dosage, the recovery of Al2O3 increased.,When the collector dosage was 900 g/t, A/S of foam was 7.06 and the recovery was 86.39%. The recovery also increased with the increase of stirring speed. When the speed of agitation mixing impeller reached 1700 r/min, the recovery was 84.56% and A/S of concentrate was 6.71. With the increase of inflation, the number of bubbles increased, the contact opportunities between bubbles and mineral particles increased, and the recovery increased. When the inflation was 0.35 m3/h, the recovery was 85.21% and A/S of foam was 6.71,. With the increase of inflation over 0.35 m3/h, the enhancement of recovery was not limited and the bubble inclusions led to the decrease of recovery of Al2O3.
