Optimizing Flotation Cells. H ow a flotation cell works . Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry.

benefits of two-stage flotation in one compact design. In the one-stage InjectaCell Compact, the reject from the primary cell is returned to a fiber recovery cell, where it is introduced directly into the layer where the fiber recovery takes place. This means that the functions of primary and secondary cells are combined in one cell.

In spite of all the advantages that can be gained, there are several challenges associated with coarse composite particles flotation. As the particle grind size becomes coarser (>250 μm), there is a sharp reduction in the particle recovery (a typical example shown in Fig. 1) due to detachment of particles from bubbles.This contributes to loss of …
