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.
Jameson Cell is also an ideal technology for non-sulfide and industrial minerals in addition to reverse flotation. In short, the Jameson Cell is an efficient, low-maintenance, high-intensity flotation technology for new plants or low-cost plant expansions.

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.
New equipment for additional energy and water savings The latest addition to Outotec's flotation equipment range is the Concorde Cell™, which sets a new benchmark in high intensity pneumatic flotation by recovering unachievable
Flotation Equipment in the mineral processing plant, mainly used for separating copper, zinc, lead, nickel, gold, and other non-ferrous metal.
Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies.
Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.
Gold Flotation Column. The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was …
Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con-ventional cells; (ii) energy-intensive pneumatic cells; (iii) column cells; …
The distribution of air throughout the entire cell volume was at one time considered essential for cell effectiveness; however, in most modern flotation cells the positive recirculation of mineral through the impeller region provides the counterpart of …
