ABSTRACT OF DISSERTATION CAVITATION NANOBUBBLE ENHANCED FLOTATION PROCESS FOR MORE EFFICIENT COAL RECOVERY Froth flotation is a widely used, cost effective particle separation process
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in For this purpose we use chemicals/reagents: , Phosphates and coal can .
In coal flotation, particles of different components of the coal such as maceral groups and mineral matter and their associations have different hydrophobicities and therefore different flotation .
Coal with high content (with higher content of undissociated mineral) of middles is difficult-to-separate, which is one of the key factors to influence coal flotation result This paper analysis, Research on difficult-to-separate coal grinding-dissociation and flotation process | SpringerLink
