摘要：

The flotation activity of RNKh-3010 reagent with respect to coal is assessed on the basis of quantum-chemical characteristics. Calculations by a semiempirical method indicate that the compounds in the reagent are strictly nucleophilic and may compete with water molecules for electrophilic adsorption centers of the coal surface. Flotation reagents may be selected on the basis of their quantum-chemical characteristics.
