For example, LiCoO 2 is naturally hydrophilic, while graphite is hydrophobic; thus, flotation separation could be considered practically. Zhang et al. applied flotation beneficiation to remove organic materials and reported 83.75% recovery of the cathode with a grade up to 94.72% . Yu et al. conducted several flotation experiments through a ...
The impurities in vein graphite can occur either as mineral inclusions such as quartz, pyroxene, pyrrhotite, pyrite, chalcopyrite, sphalerite, marcasite, chlorite, calcite, siderite, dolomite, copper or as elements incorporated into the crystalline lattice 10, 14, 24 Depletion of elements in low-carbon graphite indicates that most of the ...
The results showed that after ultrasonic treatment for 30 min, the recovery rate of graphite increased from 86.22% to 96.24%, the fixed carbon content of tailings decreased from 26.99% to 9.68%, and the fixed carbon content (84.95%) was close to that of conventional flotation (85.32%).
From 0.10 to 0.25 g, the graphite flotation recovery was decreased. From 0.25 to 0.50 g (Fig. 7 b), the graphite flotation recovery also decreased. When the β-cd weight was increased from 0.50 to 1.50 g, the graphite flotation recovery was similar to the high ash content part and reduced in comparison to the low ash content part.
