The Staged Flotation Reactor (SFR) was developed by going back to the first principles of flotation and examining how best to optimize the various phases of flotation without preconceived constraints. The result is a machine that optimizes the three stages of flotation within three separate zones, such that each zone is mutually exclusive from the requirements of the other zones. Froth drop back is minimal and tightly controlled. The constrained froth recovery zone allows for much better level control in a scavenger SFR, resulting in better recovery and upgrading.

According to Woodgrove, the Staged Flotation Reactor (SFR) was developed by going back to the first principles of flotation and examining how best to optimize the different stages of flotation without preconceived limitations. The result is a machine which optimizes the three stages of flotation into three separate zones, so that each zone is mutually exclusive of the requirements of other zones. The back drop of the foam is minimal and tightly controlled. Recovery zone "tight" pulp allows much more control in a scanning SFR, resulting in better recovery and upgrade.

Woodgrove Technologies developed the flotation cell called Staged Flotation Reactor (SFR). David mentioned the main features of the SFRcells. There are other similar flotation cells, but they have some operating and technical problems (e.g. sanding, circulating load is not handled properly, the residence time, etc).

I believe that Woodgrove design is more friendly and robust. Also, there is a very important point to keep in mind, the designers have a lot of experience in flotation, specially in the design of column cells. Some time ago, they established Minnovex, probably the main manufacturer of flotations columns.

I have been involved in two projects now that have adopted SFRs, one for gold recovery accompanying a low sulphide content and the other for pyrite recovery from a copper cleaner circuit. The latter is operating and apparently working well after some hydraulic modifications and the former has yet to be installed. Bang for buck they are more expensive than tank cells and are probably best suited to smaller plants (<1 Mt/a). They do however draw less power and have a smaller footprint. It should be noted though that they need a greater step height between cells than an equivalent tank cell train which is an important consideration for a float plant in a building but no real issue for an outdoors plant. Overall I think they could be a winner but its hard to get operating data. They don't have a patent which is why they are understandably close lipped about their products but there are some smart guys behind the technology. Ore can be piloted at their facility in Canada but there isn't really any small bench scale equivalent (1 or 2 kg) test that can be employed, they need around 80 kg as a minimum. As a cleaner stage they have a lot of appeal as they can achieve remarkable upgrade ratios which means reducing the number of flotation stages. Worth a look for your projects, especially for fine particle scenarios.

Yes, I believe it is a case of prior art which is why they guard their technology closely, fair enough. They claim that most of the energy in a tank cell, especially large ones,is spent on suspending particles rather than inducing collision, the latter being the forte of the SFR. This make sense when you look at the kW/m3 which falls away with larger cells so less energy must be going into particle attachment. Most of their blue chips are investing in SFRs so they must be taking them seriously. Spence mine in Chile tried them out but I never saw the results. Its worth talking to them to learn more about what they are up to.

The SRF Woodgrove reviews are naturally or involuntarily biased by the fact that only SFR successes are published or promoted. When SFR is tested for Ore-A and does not show improvements/gains, the test results are quietly buried.

If your flotation circuit needed extra flotation capacity and you test Woodgrove to see it if improves your situation, you are much likely to come out and say Woodgrove is a winner. Truth is you would have tested old fashion column, Jamesons, or mechanicals cells with a similar positive outcome.

I was involved in the SFR install and commissioning Greg H spoke of. (MRM days Greg) Both as the copper cleaners and latter the Pyrite roughers and cleaners. Like you Paul I was extremely sceptical....not any more. I now have a small involvement in Spence and have seen the test work.

This may be true in terms of plant applications, but not so in laboratory. I am certain there are many cases where nothing conclusive resulted from lab tests but we, the general public, will not hear about it at the CMP.

Sometimes a lower recovery rate in the small SFR pilot unit is seen and attributed to "the wall effect" ie: the adherence of froth to the walls of the test unit leading to coarse particle detachment. This wall effect is significant with small diameter pilot units and ultimately defines the lower limit of froth surface area that can be used for testing -Woodgrove explains.

Direct Flotation Reactors providing the following benefits - Up to 50% Footprint Reduction - Reduced Capital Investment - Reduced Operating Cost - Up to 50% Power and 90% Air Savings - Reduced transportation costs - Less piping, wiring and smaller MCC's - Single level staging, no step height

The Direct Flotation Reactor (DFR) is a flotation cell that works on the principle of preventing the formation of a froth and froth slurry interface. Independent bubbles are removed from the collection zone in a gas phase/slurry phase. The flotation cell has a particle collection regime in the lower half of the vessel and the loaded bubbles are recovered at the top of the vessel. The complete unit is a pressurized system. The DFR has a very low footprint due to the absence of a froth phase, the mass pull does not dictate tank size and the installation is on a single level (elevation) with no step height between cells. Being a low air system, the DFR has enhanced selectivity and like the SFR has reduced power and air consumption. No mist, dust or off-gases as the system is entirely enclosed! The system performs equally well in both rougher and cleaning circuits with equivalent or better performance than conventional flotation technology.

"The installation of the DFRs increases the efficiency and the capacity of the current cleaner circuit, which is expected to increase copper concentrate grade from about 25% to 28%, resulting in lower concentrate transportation, smelting and refining costs," the company said.

"The next stage for the mill expansion project is the installation of the third ball mill. With [that], we expect production to increase by 15% to 18% as a result of higher throughput and improved recoveries."

Copper Mountain, which owns 75% of the mine near Princeton, produces about 90 million pounds of copper equivalent annually there. It also has the permitted, development-stage Eva copper project in Queensland, Australia.
