Flotation Reagent   an overview  ScienceDirect Topics

Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers except foranic modifiers,prise mainlyanic bases and metal ions.
