If the pulp from the grinding section or conditioning tank has to be pumped to the flotation machine, it is common practice to add readily soluble frothing oils, such as cresol and pine oil, and quick-acting promoting reagents, such as xanthate, to the intake of the pump.
Jul 17, 1984· Flotation of copper is effected in the copper flotation circuit at a slightly acidic pulp pH of about 6.5 to 6.8, the pH being governed by the quantity of sulfur dioxide (SO 2) used during conditioning and aeration. A collector selective for copper in an acidic medium is employed, such as ethyl isopropyl thionocarbamate.

Conditioning time is 8 minutes at a pulp density of 40% which is then adjusted to 30% for flotation. Steam coils in the conditioner maintain the pulp at 170 degrees F. prior to flotation.
Oct 10, 2017· The conditioner pulp  is fed to a bank of rougher cells which remove most of the desired minerals as a concentrate. The rougher pulp  passes to a bank of scavenger cells where additional ...
introducing a high turbulence in the flotation pulp, the effect of such a treatment seems to be the aggregation of tiny particles reaching sizes suitable for flotation.
point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase, transported into the froth phase, and surviving as bubble-particle aggregates into the overflow.
May 05, 2010· Froth Floatation Process Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. ... The conditioner pulp …
