Abstract A hydrophobic solid such as talc graphite paraffin molybdenite sulfur highrank unoxidized coal etc does not require a collector for its separation by flotation unless contaminated by polar species so strongly that its surface turns hydrophilic To improve the kinetics of flotation a hydrophobic solid does require an addition Normally the flotation process is what is used to separate the graphite from the clay if this is not happening you may need to adjust your reagents Alternatively if the clay is finely disseminated classification will work after flotation Do you have the quality specifications physical eg sizing and chemical impurities etc
