This paper presents the results of research on the beneficiation of Akzhar phosphorites (Kazakhstan) by humic acid synthesized from brown coal. The results of scanning electron microscopy studies of microstructure and IR spectroscopic data suggest the feasibility of using humic acid as a leachable reagent for the beneficiation of low-grade phosphorites. The operating parameters of leaching by humic acid were determined. The obtained data complement the theory of using organic acids to remove carbonate impurities in the composition of phosphorites, and also provide scientific justification for further application in production.
