A process for separating a hydrophobic particulate material from an aqueous slurry containing the same is provided, which comprises the steps of: (a) mixing an aqueous slurry containing a hydrophobic particulate material with an oil having a greater density than water, to form a liquid mixture; (b) introducing a gas into the liquid mixture to produce a froth containing the hydrophobic particulate material, by flotation; and (c) recovering said froth to obtain said hydrophobic particulate material. |
