| titleOfInvention | Application of an inhibitor AA/AMPS in the removal of magnesium by positive flotation of phosphate rock |
| abstract | The application of an inhibitor AA/AMPS in the positive flotation and demagnesization of phosphate ore belongs to the field of phosphate ore beneficiation and purification technology. In this application, the inhibitor AA/AMPS is added during the positive flotation and demagnesization process of phosphate ore. Specifically, inhibitor AA/AMPS is used to prepare phosphate rock pulp, wherein the mass concentration of phosphate rock pulp is 20-25%; the mass concentration of inhibitor AA/AMPS in phosphate rock pulp is 100-140 g/t. Inhibitor AA/AMPS (acrylic acid-2-acrylamide-2-methylpropanesulfonic acid copolymer), for phosphate rock containing a large amount of dolomite, under alkaline conditions, by positive flotation process to inhibit the flotation of dolomite It can effectively increase the flotation performance difference between apatite and dolomite, and facilitate the efficient removal of dolomite. In addition, the inhibitor AA/AMPS has the characteristics of strong inhibition performance selectivity, low cost and simple use, which can effectively reduce the magnesium content of phosphate concentrate, improve the concentrate quality, and realize the flotation of high-magnesium and low-grade phosphate ores.
