Selective flotation of ilmenite from diopside using 8-hydroxyquinoline: An FeN-dominated adsorption mechanism

Selective flotation separation of ilmenite from calcium–magnesium silicate gangue remains challenging because of the weak natural hydrophobicity of ilmenite and the insufficient selectivity of conventional collectors. In this study, 8-hydroxyquinoline (8-HQ), a heterocyclic N,O-d...
