Processing of Phosphoric Solid Waste by Humic Acid Leaching Method

This article presents the results of research on leaching solid phosphorus-containing waste with humic acid. Such includes by-products electrothermal processing phosphate raw materials—phosphorus sludge and cottrel dust. Chemical X-ray diffraction analyses have been used to study their composition phase structure, according which these substances an amorphous structure. The phosphoric dust was investigated by varying main parameters. obtained data were processed using method formal kinetics features process. reaction rate constants apparent activation energy calculated, values found made it possible determine that process under is limited diffusion. scientific novelty use acid for as opposed traditional methods. new may offer improved efficiency, reduced environmental impact, a potential alternative solution waste.
