Newcrest Buys Eriez Flotation Equipment


Eriez Flotation Division (EFD) and Eriez- Australia have been selected to supply Newcrest Mining’s Cadia Valley Operations in New South Wales, Australia, with proprietary separation equipment that will be utilized to recover gold and copper from a concentrator tailings stream. The EFD equipment order includes two HydroFloat Separators and four CrossFlow Classifiers.
Eriez said its 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 increases the selective recovery of coarse particles by applying flotation fundamentals to gravity separation. According to the company, the technology can be applied to coal, iron ore, industrial minerals, base metals and sulfides. Applications include coarse particle recovery in split-feed flotation circuits and scavenging of tailings. It can also be integrated directly into grinding circuits.
Eriez’ CrossFlow is a 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 neutralization of minerals. The Cross- Flow separates particles based on hindered- settling principles. Eriez noted that its FD group has designed, supplied and commissioned more than 1,000 flotation systems worldwide for cleaning, roughing and scavenging applications in metallic and non-metallic processing operations.
