“…In turn, viscosity determines the stability and strength of the hydrocarbon fixation on a mineral. 26 It is known that viscosity is characterized and determined by the energy of intermolecular attraction via van der Waals forces and grows with an increase in these forces' action. However, the attachment of hydrocarbons to the mineral, based on adhesion and physical adsorption, also is the result of van der Waals forces, which determine the energy of intermolecular attraction.…”

BACKGROUND:The paper comprises the study of the enrichment process of potash ore with the addition of industrial oils I-8A, I-12A, I-30A to the base complex collector as an additional hydrophobizator.RESULTS: Comparative studies of flotation using liquid paraffins and industrial oils have shown the effectiveness of the latter. Physical research methods showed the effect of hydrophobizing additives on the adsorption of amine on potassium chloride crystals.CONCLUSION: The research found that introducing industrial oils into the flotation system ensures potassium chloride extraction at the same level 93.25-94.86% as when using a collective mixture with liquid paraffins. It was 10.2-11.5% higher than when using a collective mixture without apolar reagents. Thus, the best flotation performance using industrial oils was possible due to increased apolar reagent consumption. The optimal consumption of industrial oil under laboratory conditions was 20-25 g t -1 ore.
