    Kar et al. (2013) tested four different starches (soluble starch, cornstarch, potato starch and rice starch) as iron ore depressants. According to the authors, the maximum adsorption for all the four starches with hematite occurs at the pH ranging 59. However, soluble starch was found to be the better depressant at slightly alkaline pH.

  • The process of realizing iron ore beneficiation optimization

     · In reverse flotation, a large amount of water glass or an appropriate amount of starch is generally added to inhibit iron minerals. An anionic collector is used to flotate phosphate minerals. The appropriate pH value is about 10, and the heating of the slurry is beneficial to improve the phosphorus removal effect.
