| Abstract: | Based on the characteristics of Yunnan phosphate rock, with oleic acid as collecting agent, sodium silicate as inhibitor, sodium carbonate as regulator, the direct flotation of phosphate rock containing silicon and calcium is carried out for desiliconisation. The process is discussed from the ore properties, flotation reagents and desiliconisation mechanism, so as to enhance the selectivity of flotation reagents, achieve the goal of improving the grade of phosphate concentrate. |
