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.
In conventional flotation cells a certain amount of energy is required to meet the basic requirements for flotation (air dispersion, solids suspension and particle-bubble collision). This paper investigates how that energy is dissipated in the flotation cell to determine the most efficient use of the imparted energy.

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 …
The flotation machine, also known as a flotation cell or flotation separator, is a device used in mineral processing to separate valuable minerals from gangue (unwanted material) based on their differences in hydrophobicity (ability to repel water) and buoyancy.
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.
Flotation Equipment in the mineral processing plant, mainly used for separating copper, zinc, lead, nickel, gold, and other non-ferrous metal.
The Jameson Cell technology is an established robust and efficient high intensity flotation technology which has been continuously developed and improved over two decades. Its high capacity, small footprint and low maintenance requirements have made it more or less a standard flotation technology in the Australian coal industry.
