This study explores the key physicochemical factors affecting the hydrophilic characteristics of iron mine blasting dust (BD). The BD is separated into an unwetted part (UWBD, hydrophobic part) and a wetted part (WBD, hydrophilic part). Its particle size, true density (TD), pore parameters, mineral composition, and surface compounds are comprehensively characterized and compared. The results ...
