Real systems do not fulfill ideal conditions, mainly because of feed variation or disturbances. "Before considering disturbances to flotation specifically," Kabemba says. "It is important to emphasise the interlock between grinding and flotation, not only with respect to particle size effects, but equally to flotation feed rate variations. The grinding circuit is usually designed to produce the optimum size distribution established in testing and given in the design criteria. When the product size alters from this optimum, control requires either changing feed tonnage to the circuit or changing product volume, with either causing changes in flotation feed rates."While grindability changes due to the variation in ore properties are disturbances to the grinding circuit, they generate feed rate changes as disturbances to the flotation circuit. The variations in ore properties which affect flotation from those assumed in the design criteria must therefore necessarily include grindability changes

"This reflects important differences in flotation machine characteristics between the two processes. Grinding circuits are built and designed with fixed total mill volumes and energy input, so the grinding intensity is not a controllable variable, instead grinding retention time is changed by variation of feed rates. In contrast, the flotation circuit is provided both with adjustable froth and pulp volume for variation of flotation intensity by aeration rate or hydrodynamic adjustment. Reagent levels and dosages provide a further means for intensity control."

One recent trend has been towards larger, metallurgical efficient and more cost effective machines. These depart from the simpler tank/mechanism combination towards design which segregates and directs flow and towards providing an external air supply for types which had been self aerating and towards the application of hydrodynamic principles to cell design, like the Delkor BQR range of flotation machines, initially the Bateman BQR Float Cells

Bateman has steadily developed the BQR flotation cells which have been in application for the past 30 years, and with its acquisition of Delkor in 2008, decided to rebrand the equipment into the Delkor equipment range. Kabemba explains that BQR cell capacities range from 0.5 to 150 m3 currently installed and can be used in any application as roughers, scavengers and in cleaning and re- cleaning circuits

Flotation machine is applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation, fine separation and floatation, so the useful ore are reclaimed

The flotation machine has the advantages of large air-absorption capacity and low energy consumption. Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow. The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent. There is self-control device on the surface of mineral slurry, so it is easy to adjust it. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurry

Stawell gold mine in co-operation with Outotec Services completed a flotation circuit upgrade on time and on budget last year that, instead of the projected 3.5% improvement, resulted in an increase of 4.5% since the project was completed. Payback was also impressive, occurring within less than four months

Flotation has been at the heart of the mineral processing industry for over 100 years, addressing the ‘sulphide’ problem of the early 1900s, and continues to provide one of the most important tools in mineral separation today.  The realisation of the effect of a minerals hydrophobicity on flotation all those years ago has allowed us to treat oxides, sulphides and carbonates, coals and industrial minerals economically, and will continue to do so in the future

There have been a number of important changes in the industry over the years as flotation technology and equipment have advanced.  Xstrata Technology considers “the most noticeable has been the increase in sizes of the flotation machines, from the multiple small square cells that were initially used, to the 300 m³ round cells used today that are the norm in large scale plants

“Other changes have been more subtle, but equally as important. One of these has been the design of the flotation circuit to make the most of the liberation and surface chemistry effects of the minerals. In a lot of these situations it is not a matter of ‘bigger is better’, that will make the process work, but being smarter in the application of flotation technology.”

Xstrata Technology is one company that believes the smarter use of flotation machines can deliver big improvements in plant performance. Through its use of the naturally aspirated Jameson Cell, Xstrata Technology has been making inroads into the processing of more complex ores. Having a small footprint, and using the high intensity mixing environment of slurry and naturally induced air in a simple downcomer, the Jameson Cell provides an ideal environment for the separation of hydrophobic particles and gangue, it says. The small footprint of the cells also makes them ideal to retrofit into a circuit especially where space is tight

While the cell has been included in some flotation applications as the only flotation technology such as coal and SX-EW, the main applications in base metals have seen the cell operating in conjunction with conventional cells. The combination of the two technologies enables the Jameson Cell to target the quicker floating material, while the conventional cells target the slower floating material. “Such a combination provides a superior overall grade recovery response for the whole circuit, than just one technology type on its own,” Xstrata Technology says. Below are some of the duties for which the Jameson Cell can be used
