    Apr 01, 2016 3D models of clusters of antimony and bismuth sulfides were constructed. For these models, the charges of individual atoms and the electron populations of s-Pop, p-Pop, and d-Pop orbitals were determined. Collector activity evaluation prediction (CAEP) was made for a number of proposed reagents attached to atoms of clusters of minerals. CAEP characterizes the activity of a collector: the

    Mar 15, 2021 Some of the reasons argued by Qin et al. (2017) that contribute to the poor floatability of antimony oxide are: the relatively low hardness of these minerals, and the consequent trend to overgrind them and create slimes that affect flotation efficiency; the possible similarity in the flotation behaviour between quartz and antimony oxides such as cervantite; and the tendency of antimony oxides to
