Metso technology and design provides energy efficient flotation
Optimal mineral recovery in a flotation circuit depends on the capacity to adapt to metallurgical variability in the ore being processed. Recognizing the need for a solution that addresses these challenges Metso has made several advances in flotation design and technology.
Combining the benefits of circular cells with the unique features of the patented DVtrade mechanism the RCStrade Reactor Cell System flotation technology has been developed to create ideal conditions to maximize flotation performance for all roughing cleaning and scavenging duties. The cell can be modified to handle high density slurries.
Metso RCStrade flotation machines have made several advances in flotation design and technology.
Maximize bubble-particle contact within the mechanism and the flotation tank leads to enhanced performance. Effective air dispersion and distribution throughout the cell volume helps in smooth froth surface and removal.
Our RCStrade flotation machines are built with efficient air and level controls with controlled aeration rate at each cell. The pneumatically operated dart valves help in effective pulp level control followed by accurate measurement with ultrasonic level sensor and float.
Development of the all new REFLUX Flotation Cell RFC has been an extension of the already established development partnership with the University of Newcastle working closely with Professor Kevin Galvin who is Director ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals. This partnership has already seen the successful development and commercialisation of the REFLUX Classifier RC with a similar commercialisation path being envisioned for the new REFLUX Flotation Cell.
The RFC joins the wider suite of REFLUX technologies along with the REFLUX Classifier which is a hydraulic classifier that separates particles using gravity based on a difference in density or particle size. It combines a conventional fluidised bed separator with a set of parallel inclined plates that form lamella channels and this lamella technology is what is implemented in the RFC. That said the REFLUX Flotation Cell utilises flotation principles instead of gravity principles as with the RC.
FLSmidth says it has seen a good technology transfer of the RC in terms of the lamella plates which enhances segregation to implementation in flotation in the form of the RFC. In the RC the lamella plates allow for much higher separation efficiencies effectively producing a much steeper partition curve when considering density and sizing applications. In the RFC having this allows for advanced bubble slurry segregation allowing the RFC to operate in higher air fractions with higher air flux and higher throughput.

While coal has historically been the initial focus of the technology development recent testing in copper moly gold iron ore and graphite applications have all produced similar results in terms of improved grade and recovery along with a reduction in required flotation retention time. In some cases we are producing not only a higher grade product at a higher recovery rate but also in a shorter timeframe.
A comparison to the Imhoflot cell shows similarities in the initial first high intensity precontact step but beyond this FLSmidth says the unique nature of the RFC segregation comes into play to bring performance well beyond what is possible with any other cell. All other flotation technologies also have froth recovery limitations the RFC doesnt really have a defined froth-pulp interface further promoting recovery.
Christodoulou adds The unique nature of the design and use of the lamella plates means this isnt something you can retrofit onto existing conventional cells. To start with we see RFC flotation being able to work to offload overloaded circuits in coal and base metal cleaner circuits then start to replace column flotation circuits and ultimately replace banks of open conventional cells though there is still some way to go for full market acceptance before we get to that point.
A number of trials have already been carried out with a pilot scale system that is similar in scale to the lab scale system except that the pilot testing has been on a continuous basis using a continuous feed. In addition to the pilot FLSmidth and the University of Newcastle are currently trialling a two metre RFC machine in an Australian coal application. This full-scale evaluation is set to be completed early 2021.

Flotation Machines Mining Machine Supplier Jxsc. In the case of ore easy separated and a small amount of air inflation required may choose a mechanical flotation machine if the minerals with coarse size proper to choose the KYF BSF ore CLF type whats more when in case of ore easy separated fine particles high grade low PH flotation column is the best especially in the concentrating process.
Fine uniform bubble dispersions with bubble size typically ranging from 400 to 1200 microns are generated by the sparger system. The bubble suspension is introduced near the column base and bubbles rise throgh the column collection zone.
There are many factors that can affect your flotation process. The two aspects that have the strongest impact on a flotation circuits efficiency and performance are metallurgical recovery and flotation cell availability. Fluctuations in feed characteristics can lead to recovery losses. The inability to handle changes in feed size and mineralogy can result in the loss of availability. At FLSmidth we have developed solutions to these challenges and more.
Every project we take on is engineered to fit your operation regardless of the size. Our expert solutions range from equipment only to the entire flotation island including all auxiliary equipment tanks pumps piping blowers etc.. Regardless of the project scope our selection of flotation machines comes equipped with a range of drives dart valves and automation options.
