P22 – Counter Current Washing in Flotation of Minerals to Establish the Limits of Cleaning

Closing Date: 31 December 2020Apply Now


PhD Scholarship

Supervisor: Laureate Professor Kevin Galvin - The ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals is seeking creative and innovative PhD applicants to join our national collaborative Centre, to develop transformational technologies to reduce energy and water consumption and increase metals recovery. This project will investigate the benefits of counter current washing of flotation product using the Reflux Flotation Cell.

The Centre’s inclusive and equitable culture is supported by specific equity and diversity initiatives, which will support all members to achieve their career goals.

The industry needs to develop more efficient separation technologies in order to increase the product grade, and in turn reduce downstream energy consumption. A novel flotation technology known as the Reflux Flotation Cell will be investigated in order to quantify the limits of cleaning achievable in key applications including graphite and copper. Those findings will be compared with the expectations from scanning electron microscopy.

This work may lead to new ways to limit the need for overgrinding, thus increasing the mineral recovery, while reducing energy and water consumption. Other benefits could arise through increased selectivity from the new reagents to be developed within the centre. The work might also lead to significant simplification of flotation plant and an order of magnitude reduction in the footprint by combining the counter current washing with a significant increase in process intensification.

This is a major Centre of Excellence project involving manufacturer FLSmidth and research collaborators from the University of Newcastle and Queensland.

This project has the potential to deliver significantly improved product grade, and hence transformational change to deliver on Thematic Objective 2. Old tailings dams might be reprocessed to recover minerals for metals, allowing and even funding the rehabilitation of the land.
