TL;DR: In this paper, the effect and mechanism of the introducing iso-propanol substituent on amine collectors were investigated by surface tension measurements, molecular dynamics simulation (MDS), and density functional theory.

TL;DR: A novel surfactant N-dodecyl-isopropanolamine (NDIA) has been synthesized and utilized as a collector for flotation separation of quartz from hematite as discussed by the authors.

TL;DR: In this article, the adsorption of calcium ion on quartz (101) surface in aqueous was studied through DFT calculations, which indicated that the formation of Ca-Oq (calcium ion in oq and O atom on quartz surface) bond and hydration process of quartz surface were both closely related to calcium ion adsorction on the quartz surface.

TL;DR: In this paper, a hydroxyl-containing polyamine cationic surfactant was designed and screened with the assistant of computer simulation (molecular dynamics simulation and density functional theory (DFT) calculation) to enhance the separation efficiency in the reverse flotation system of hematite ore.

TL;DR: In order to improve the flotation separation efficiency of bastnaesite from barite and calcite, a novel collector, octylamino-bis-(butanohydroxamic acid) (OBHA), with large molecular structure and two functional groups was synthesized based on the molecular design of flotation reagents theory.
