A novel surfactant S-benzoyl-N,N-diethyldithiocarbamate synthesis and its flotation performance to galena

- A novel surfactant BEDTC was first introduced as galena flotation collector.
- BEDTC exhibited superior collecting power to galena against sphalerite.
- BEDTC has two active centers to mineral surfaces.
- BEDTC molecules formed two distinct adsorption geometries on galena surfaces.
