Improving flotation separation of apatite from dolomite

In the apatite flotation process, carbonate minerals especially magnesium-bearing dolomite are easy to enter into apatite concentrates, reducing the quality of concentrate products and causing excessive acid consumption in downstream processing.

Effect of Sodium Chloride on Dolomite Flotation

With the conventional processing techniques, dolomite, usually reported as weight percent MgO, cannot be selectively removed from apatite, the phosphate mineral. More than 1% MgO in the final phosphate concentrate would present problems during chemical processing to manufacture phosphoric acid, an intermediate chemical used in the production of fertilizers. The presence of MgO in quantities

Development of Reagent Schemes for Reducing MgO Content in

These techniques could reduce MgO content in the final concentrate by 20-40%. The flotation process could achieve a concentrate with the lowest MgO content, but it is the most expensive approach. Adding a dolomite is inexpensive and easy, but the effect is limited. Overall, scrubbing may be the most promising technology for this purpose.

Selective adsorption of an eco-friendly and efficient

Additionally, 87.41% of fluorapatite was recovered in the froth concentrate while only 21.05% of dolomite was floated, indicating that PBTCA displayed a strong depression on the dolomite flotation, thereby improving the flotation selectivity in the dolomite-bearing fluorapatite ore flotation.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
