Factors responsible for the effective action of collectors in the extraction of the organic matter of coal are presented and substantiated. It was established that molecular electronegativity is an integral quantum-chemical test for the flotation act

The quantum-chemical characteristics of molecules in coal’s organic mass, water, and complexes formed in the interaction of the coal surface with water are calculated. Results obtained by semiempirical root-mean-square calculation indicate that wat

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
