Wolfram tailing re-selection process is mainly used spiral chute and centrifugal ore separator to roughing, shaking table and flotation to cleaning. 7. Phosphate Tailings: Siliceous collophanite mainly include quartz siliceous minerals in gangue mineral, so the floatability of gangue is larger than valuable mineral. 8. Graphite Tailings：
Herein, a novel graphite/sulfur iron tailing composite was applied as a peroxydisulfate (PDS) activator for rhodamine B (RhB) degradation in the water. The superior catalytic efficiency of graphite/sulfur iron tailing was achieved through radical (SO4•− and •OH) and non-radical (1O2) processes according to the radical quenching …

In microcrystalline graphite flotation, majority of sericite fines was recovered into concentrates as a result of froth entrainment, partly recovered by entrapment, ... and the froth product was scraped out as concentrates and the pulp left in cell was tailing; finally, the concentrates and tailing were dewatered, dried and weighed. ...
The above findings revealed that the lowest LOI of the tailing in conventional flotation was 5.72%, which still surpassed the grade I fly ash requirements. However, carrier flotation could decrease the LOI of the tailing to <5%, satisfying the grade I fly ash standards, and even reach a minimum LOI of 4.09%. carrier flotation resulted in a ...
