Microscale insights into the influence of grinding media on spodumene micro-flotation using mixed anionic/cationic collectors
文献摘要:
Here,the influence of grinding media with different shapes on the flotation performance of spodumene and its potential mechanism from microscale insights was investigated using a single mineral flotation experiment,X-ray diffraction (XRD) test,scanning electron microscopy combined with energy dispersive spectrometry (SEM-EDS),atomic force microscope (AFM) and X-ray photoelectron spectroscopy (XPS).The flotation data indicated that under anionic/cationic (sodium oleate (NaOL)/DDA) collectors system,the rod milled spodumene has a higher floatability than ball milled ones.XRD results confirmed that rod medium makes spodumene exposed more {110} and {100} planes,while ball medium makes spo-dumene exposed more {010} planes.The typical anisotropic surface of spodumene makes the surface of rod milled spodumene possess more Al sites,further confirmed by SEM-EDS and XPS results.Additionally,it was found that the rod milled spodumene presents a larger value of elongation and flat-ness,which are parameters closely related to bubble adhesion.AFM analysis indicated that rod milled products have a rougher surface,while ball milled products have a smoother surface.Consequently,the rod medium enhanced the adsorption of NaOL/DDA on the spodumene surfaces.This work provides theoretical guidance for optimizing the separation of spodumene from the perspective of grinding.
