Abstract
Effect of mechanical activation of brown and oxidized coal in the presence of alkaline reagent and abrasive material in different concentrations was demonstrated. Solid-phase mechanochemical reactions of humic acids with the salts of heavy metals were carried out. The features of structural transformations of humic acids during mechanical activation were revealed.
