Sanding in flotation cells
Sanding can occur for many reasons, the two main and most common being; 1) poor classification ahead of flotation allowing oversized material to enter the cells, and 2) impeller wear leading to poor mixing in the cell.
Synergistic effects of Reflux Flotation Cell's
Apart from the entrainment of normal fine particles during flotation, clay minerals with a particle size normally smaller than 5 μm also undergo aggregation, generating aggregate structures which compound the entrainment problem. The aggregation behavior of clay minerals is attributed to their complex crystal structure, …
Optimizing Flotation Cells
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.

Column Flotation Cells
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
