The article presents the theoretical and experimental studies aimed to develop a scientific basis for mineral dressing with improved pretreatment and selective flotation. It is found that nonmechanical energy input in the form of a flow of accelerated electrons in ore pretreatment enhances performance of processing of rebellious mineral raw materials. The features of a unit flotation process are discussed in terms of disclosure of nature of collectability and selectivity of a reagent and their connection with the molecular structure of a hydrocarbon fragment and a whole molecule. The notion of the collecting activity of reagents is introduced, and the flotation aggregate criterion is proposed. The promising applicability and efficiency of low-grade manganese ore in removal of organic and inorganic contaminants from water by adsorption with a view to mitigating the adverse environmental impact exerted by mineral mining and processing on natural water bodies is demonstrated.
The study was carried out in the framework of R&D project, State Certificate No. AAAA-A17-117092750073-6.
