一种白钨矿浮选组合药剂及其使用方法
By using the combined collector DBOA/S465 and the combined inhibitor PSS/ATMP, the problems of poor collector selectivity and large inhibitor dosage in scheelite flotation were solved, achieving efficient separation of scheelite from calcium-bearing gangue minerals, improving the concentrate grade and recovery rate of scheelite, and reducing production costs.

AI Technical Summary
In the existing flotation process for scheelite, the collector has poor selectivity, the concentrate grade is low, the amount of depressant used is large, and the inhibitory effect on calcium-bearing gangue minerals is poor, resulting in low separation efficiency and high cost of scheelite and calcium-bearing gangue minerals.
A combination of collector DBOA/S465 and inhibitor PSS/ATMP was used. DBOA is sodium brominated oleate, S465 is Surfynol 465, a gemini nonionic surfactant, PSS is sodium polystyrene sulfonate, and ATMP is aminotrimethylene phosphonic acid. By forming a collector bilayer film and chelating, the selectivity of scheelite and the inhibition of calcium-bearing gangue minerals were improved.
It improved the concentrate grade and recovery rate of scheelite, reduced the amount of inhibitor used, achieved efficient separation of scheelite from calcium-bearing gangue minerals, and reduced production costs.
