| Abstract: | Methods for introducing humic acid into granular multicomponent phosphogypsum-based ameliorants are elaborated. The influence of modifying additives of humic acids on the physicochemical and performance characteristics of phosphogypsum granules containing crystalline solvates of calcium sulfate, and on the process of leaching different extrinsic components from the granules, were studied. |
