These collectors are characterized by a hydrophilic group usually composed of divalent sulfur atoms inside the molecule, while the hydrophobic group has a small molecular weight and has a trapping effect on sulfide minerals, but has no trapping effect on gangue minerals such as quartz and calcite . Therefore, when such a collector is used for flotation of sulfide ore, it is easy to separate and remove gangue such as quartz and calcite. It mainly represents xanthate, black medicine, amino thioformate, thiol, thiourea and their corresponding esters.
