A quick analysis discussed below shows that roughly 60–80% of the total 25-year cycle costs for a large flotation machine are spent on energy while the initial investment comprises less than 10%. As a result, if a small saving in investment is achieved by compromising energy efficiency, it can quickly turn into big losses in operational costs.

In flotation machines, which still prevails in flotation practice, the operation takes place in a highly turbulent flow (Re D 2 ≈10 6 –7×10 7 in industrial-scale machines). Therefore, the modelling of a flotation process (macroprocess) and its microprocesses necessitate the application of essential results of the statistical turbulence theory.

Research and development into the application of machine vision in froth flotation systems has continued since its introduction in the late 1980s. Machine vision is able to accurately and rapidly extract froth characteristics, both physical (e.g. bubble size) and dynamic (froth velocity) in nature, from digital images and present these results to …

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

The cell can be modified to handle high density slurries. RCS flotation technology provides excellent air dispersion, producing fine even sized bubbles. Maximum flotation recovery …

Flotation machine is the also called flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the ore pulp treated by adding reagents is stirred and aerated to selectively fix some of the ore particles on the bubbles. It floats to the surface of the ore pulp and is scraped ...

Flotation machine, also called flotation cell, is the equipment to complete the flotation process. It is widely used for the rough, fine and reverse flotation operations of copper ore, lead ore, zinc ore, nickel, molybdenum and other non-ferrous metal, ferrous metal and nonmetal minerals. The types of flotation machine mainly include mechanical ...

The latter is an advanced flotation machine (Nova Cell™) which shows savings in operating costs of grinding energy and media by 40% and 12%, respectively (Jameson and Emer, 2019). This flotation cell drastically reduces the mining industry's water and energy consumption by increasing the flotation's upper particle size limit.

Flotation is a dynamic process and the efficiency is directly related to the time material spends in the machine. To fully analyze this process, the distribution of the time it takes for the material to proceed from the inlet (s) to the outlet (s) has to be known. This distribution is the best indication of the flow patterns in the vessel.

Bubble sizes that are discussed in the flotation area of current literature are usually in four size groups. The typical bubble size in conventional flotation machines is found to be in the range close to 1 mm, such as the data reported by several researchers which were 600–2500 μm (Rodrigues et al., 2007), 800–1600 μm (Shao, 2004), and …
