EFD is the leading supplier of with over 170 installations worldwide. Our commercial columns are up to 6 metres in diameter, and are being used in most of the world's largest copper concentrators. Our range of sparging technologies allow us to choose the right sparging technology for your application. We have also developed the HydroFloat, which is now being evaluated for selectively floating coarse copper sulfides, which is creating a paradigm shift about how much grinding energy is required for base metal concentrators.
Our rotary slurry splitter (RSP) is also used in a number of copper applications such as Vale's Sossego (pictured to the right) to evenly and accurately split slurry feed between a number of parallel columns.
