文摘

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 lower CAEP, the more preferable the interaction of the collector and the more efficient the flotation reagent. For flotation of antimony and bismuth minerals, a number of promising collectors were recommended.
