Eriez Flotation Division (EFD) and Eriez-Australia will supply Newcrest Mining’s Cadia Valley Operations in New South Wales, Australia, with proprietary separation
equipment. This will be utilised to recover gold and copper from a concentrator tailings stream.
The EFD equipment order includes two HydroFloat™ Separators and four CrossFlow® Classifiers.
EFD has designed, supplied and commissioned more than 1000 flotation systems worldwide for cleaning, roughing and scavenging applications in metallic and
non-metallic processing operations.
“With strength and expertise in process engineering, equipment design and fabrication, EFD has assumed a leadership role in meeting increasing global demands for minerals flotation systems—especially for coarse particle recovery,” says Eriez-Australia managing director Jaisen Kohmuench.
“Our team has successfully led projects, operations and businesses related to mineral processing across the globe. This gives us the perspective and depth of
experience to be a trusted equipment vendor and partner to operations, engineers and mining companies throughout the world.”
HydroFloat Separators for coarse particle mineral concentration deliver the capacity of a density separator while maintaining the selectivity of a flotation
device.
Using a novel aeration system to disperse fine bubbles into a fluidized-bed environment, the HydroFloat Separator significantly increases the selective recovery of
coarse particles by applying flotation fundamentals to gravity separation.
This technology can be applied to coal, iron ore, industrial minerals, base metals and sulphides. Applications include coarse particle recovery in split-feed
flotation circuits and scavenging of tailings. It can also be integrated directly into grinding circuits.
Eriez’s CrossFlow Separator is a highly efficient hydraulic classifier for the separation of material based on particle size, shape and/or density. This technology
can also be used for desliming, counter-current washing and acid neutralisation of minerals. The CrossFlow separates particles based on hindered-settling
principles, providing an economical and efficient means of classifying material such as silica and frac sands, mineral sands and industrial minerals.
EFD is a world-leader in advanced flotation technology. Formerly known as Canadian Process Technologies, Inc, EFD is a wholly-owned subsidiary of Eriez
Manufacturing Co. EFD provides advanced testing and engineering services in addition to sparging and column flotation equipment for the mining and mineral
processing industries.
