Highly efficient flotation separation of wolframite from calcite using a dual-ligand hydroxamic acid collector: Experiment insight and mechanism exploration

Aiming at the problems of traditional collectors in the flotation of tungsten ore, such as weak collecting ability for wolframite and difficulty in effective separation from calcium-bearing gangue (e.g., calcite), a dual-ligand hydroxamic acid surfactant, sebacoyl hydroxamic acid (SHA), was synthesi...
