Flotation REFLUX™ revolution - International Mining 


Lance Christodoulou, Global Product Manager - Flotation at FLSmidth spoke to Paul Moore at IM about the revolutionary REFLUX™ Flotation Cell (RFC™) which is being developed together with the University of Newcastle & brings a unique design that is capable of achieving higher grades, recoveries and throughputs of any other flotation cell currently available.

Upscale and commercialisation planning begins after REFLUX™ Flotation Cell (RFC) wins grant funding from European Union body, EIT


MINING NEWS RELEASE, COPENHAGEN, DENMARK

 

  • A consortium led by FLSmidth was awarded a EUR5.4 million grant by EIT RawMaterials to continue the work of reducing energy and resource use in the global mining industry.
  • The project entails a new flotation process called RFC – Reflux Flotation Cell.
  • The opportunity presented by the grant will accelerate the commercialisation of the RFC technology, which has potential across various commodities and flotation applications.
  • The RFC-Upscaling project will run from 1 June 2021 until 1 June 2024.

The ambition of reducing emissions in the mining industry has driven FLSmidth to a number of research and development partnerships with customers, third parties and academic institutions around the world. One of the most promising joint projects led by FLSmidth has received a comprehensive grant from the European Institute of Innovation and Technology (EIT), a body of the European Union, to continue the work of reducing energy and resource use in the global mining industry.

The annual EIT RawMaterials KAVA Upscaling Projects grant has been awarded to the REFLUX™ Flotation Cell (RFC™). Preliminary planning for the project has now been started by a consortium of two mine sites, chemical companies and two universities led by FLSmidth. The goal is to upscale the RFC technology and accelerate commercialisation during the three-year project. This will involve pilot and full-scale testing and eventual sales of full-scale equipment for the copper and iron ore industries, among others.

The innovative RFC technology, invented by Professor Kevin Galvin of the University of Newcastle in Australia, has an entirely new internal design compared to traditional flotation methods. The result is much higher throughput with simultaneously improved separation efficiency. Since flotation is a key process area that impacts upstream comminution and downstream dewatering, there is huge potential to save energy and resources through innovations in flotation process technology.

FLSmidth was awarded EUR2.8m of the total EUR5.4 million grant by EIT RawMaterials through a competitive application process. The RFC-Upscaling project will run from 1 June 2021 until 1 June 2024. More information about the project can be found on the EIT RawMaterials website: https://eitrawmaterials.eu/project/rfc-upscaling/.

I firmly believe that the solutions to the vast environmental challenges we are all facing must come from technology. I am delighted that we, together with our partners, can deliver a solution that helps in achieving this goal.

Thank you to Wayne Douglas and the Mining R&D team for their hard work in securing the grant.
