Eriez’ CavTube columns, which are effective for the recovery of ultra-fine particles, are an integral component of Arq’s micro separation process. The cavitation tube sparging system – known as CavTubes® – features a design based on hydrodynamic cavitation. This novel approach results in nucleation of ultra-fine bubbles on the particle surface which act to facilitate flotation kinetics by improving subsequent attachment of larger bubbles for separation. As a result, the flotation rate of ultra-fine particles is greatly improved.
Eriez Flotation US Director of Operations, Andrew Hobert, commented: “In addition to the benefit of our cavitation tube sparging technology, column flotation cells offer superior metallurgical performance due to the use of both wash water and a deep froth phase.” He added: “In the Arq application, these advantages minimise entrainment of ultra-fine mineral matter into the froth product.”
Tom Tudor, Arq’s Head of Brand and Communications, said: “Arq are able to transform an environmental liability into a cleaner, more efficient source of low cost energy through the innovative application of world class technologies from multiple industries.”
