    • Abstract
  • Through single mineral flotation experiment, artificial mixed minerals flotation experiment, adsorption capacity and infrared spectrum measurement, the flotation behavior of tungsten minerals and the adsorption mechanism on tungsten minerals surface of benzohydroxamic acid (BHA) and cocamine (ACO) combined collector were studied. The results show that in the range of pH=2.0-12.0, the BHA-ACO combined collector has a stronger collecting ability than BHA on tungsten minerals. The optimum pH value of the combined collector is 10.0, and the recovery rate of wolframite flotation and scheelite flotation is 79.80% and 76.68%, which are much higher than the recovery rates of wolframite flotation and scheelite flotation of 37.09% and 53.96% when BHA is used alone. ACO could increase the adsorption capacity of BHA on the surface of tungsten minerals, and the BHA-ACO combined collector had significant synergistic effect on wolframite and scheelite surface, resulting in strong chemical adsorption.
