It investigated the impacts of pulp pH and redox conditions on the wettability, zeta potential of mineral particle surfaces, and surface oxidation behaviors of minerals, analyzed the redox regularity of minerals, clarified the flotation behaviors of stibnite and arsenopyrite under different depressant systems, and realized the selective depression of arsenopyrite. Commonly used industrial characterization techniques including X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and inductively coupled plasma mass spectrometry (ICP-MS) were adopted to acquire various physicochemical property data for the separation of stibnite and arsenopyrite, ensuring the efficiency and stability of data acquisition. Based on the above data, the flotation behaviors of stibnite and arsenopyrite under different depressant systems were clarified, the selective complexation mechanism between depressants and mineral surfaces was revealed, and a micro-area selective regulation technology for mineral surface oxidation and depressant complexation was developed, achieving selective depression of arsenopyrite. The aforementioned research contents provide technical references for the green development and utilization of stibnite and arsenopyrite. This dataset primarily contains raw and calculated data from multiple research aspects: the crystallochemical differences and reagent adsorption differences between stibnite and arsenopyrite in the micro-area selective oxidation-complexation regulation for green and efficient separation of antimony and arsenic; the screening of efficient reagents for flotation separation of stibnite and arsenopyrite; the flotation behaviors of stibnite and arsenopyrite under different pH values and depressant actions; and the interaction mechanisms between stibnite, arsenopyrite and depressants. The total data volume is 126.64 MB.
