The modification of the phosphogypsum granuls by the humic acids

Abstract

The methods for the incorporation of the humic acids ( as stimulatory to growth of plant) into the phosphogypsum granuls worked out. It was investigated the humic acids addition effect on the phosphogypsum granuls compression strength, water resistance, on the dust formation and the leaching of the bioactive elements (Cu, Zn, Mn) from granuls.
