froth flotation. this froth prevents bursting of the bubbles and release of the cu mineral particles back into the slurry. the froth overflows the flotation cell, often with the assistance of paddles fig. 4.2 , and into a trough. there it collapses and flows into a collection tank.
this configuration may change completely depending on the ore type, particle size and product demands. once the ore particle size is appropriate for column flotation, circuits may vary from having all cells as mechanical cells to all of them as columns, as well as various combinations of both. figure 4 and 5 present some examples of real circuits.
sf flotation cell is a mechanical agitation type flotation equipment with self-slurry suction and self-air suction
improvement: bf flotation cell has two types: type i and type ii. type i is improved as suction cell referring to model sf; type ii is improved as direct flow cell referring to model jjf. both are briefly called model bf. a mechanical agitation type floatation cell unit with self-air suction and combination of slurry suction/no slurry suction
coal flotation was conducted in a 1.5 dm 3 jk batch flotation cell using de-ionised water. for each test, 100 g dry coal sample was added into 0.7 dm 3 water and stirred for 3 min at an agitation speed of 1200 rpm to achieve the sufficient dispersion of coal particles.
above are illustrations of three flotation cells. 14.2 m3 500 cu.ft cell 2.8 m3 100 cu.ft cell 1.4 m3 50 cu.ft cell note the nominal depth a of the flotation separation zone in all the cells is the same in each case. intense agitation and aeration occur in the mixing zone at the bottom of the cell.
of flotation cells in typical industrial circuits. the reason for the difficulty lies in the complexity of the many micro processes that combine to produce the overall result which is the separation of different mineral species by virtue of the differential surface conditions that can be induced on the
copper flotation cell machine and its three types. new type flotation cell for copper ore tgcg. there are three types of flotation stages rougher, scavenger and cleaner.
4 dr flotation shallow flotation in deep cells the top vertical recirculation of pulp used by the dr flotation machine is ideal for hand-ling all types of pulp containing coarse and abrasive solids or finely ground solids in principle, the cell functions as a shallow flotation cell as the air and pulp are hydrau-
both types can be used to modernize existing columns to improve column flotation results. figure 5. outotec sonicsparger jet. figure 6. outotec sonicsparger vent. application of columns. in reverse flotation, columns have been used to remove fine gangue in a selective way, guaranteeing a high recovery of the main mineral in the underflow.
