Froth flotation circuit design and basic testwork requirements. The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineral laden froth. The remaining unfloated mineral slurry will be discharged as tailings.

Abstract. Laboratory agglomeration flotation tests were used to evaluate the recovery of residual bitumen from a sample of Suncor oil sands fine tailings, using ground coal as a bitumen absorbent. To improve its effectivness, the coal was preconditioned with no. 2 fuel oil, subjected to 30 s high shear mixing and collected by flotation over 3 min.

Principle of operation. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector).
The underflow material is pumped into a conditioning tank, where flotation reagents (collector, frother and dispersant) are added and mixed with the slurry. From the conditioner, the slurry is pumped to the rougher flotation circuit. The tailings (non float) product

Rougher flotation is the first step in the separation of concentrate from tails. Rougher tailings go directly to the tailing thickening circuit, while the concentrate moves on to a regrind mill and then to four stage of cleaning in a flotation circuit.
Rutile is recovered from copper ore tailings by means of a froth flotation process comprising (a) flotation of sulfides and carbonates at a pH of about 9 to 10, using sodium isopropyl xanthate and sodium oleate as collectors, and detrine as rutile depressant, and (b) flotation of rutile from the resulting tailings at a pH of about 2 to 3, using hydrofluoric acid as a rutile selectivity
Froth flotation relies on differences in the surface chemistry of the ore and waste grains. Sulfide ores in particular are more readily wet with oil than water. Grains of clay, sand, and other seabed detritus have the reverse tendency. Typically something like pine oil might be used to wet the mineral grains.

Pyrite Tailings Recovery by Flotation. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a suitable source of sulphur dioxide for the manufacture of sulphuric acid.
