Flocculation/flotation to improve recovery of fine minerals
Speaker: Professor George V Franks, Professor, University of Melbourne
Abstract: Fine (<20 micron) valuable particles are often not collected by froth flotation and go to tails. Commercial polyacrylamide flocculants can be used to selectively aggregate fine valuable minerals such as hematite, chalcopyrite and spodumene. The aggregates can be made hydrophobic and potentially recovered by froth flotation. The additional value recovered can be on order 10 to 50 million dollars per year depending on the commodity and mine throughput.

About JKMRC Friday Seminars 2023
Welcome to the 2023 Series of the JKMRC Friday Seminars. The list of presentations will aim to cover a range of topics related to the minerals sector from decision making in exploration, new mineral processing technologies, social licence to operate and mine closure.
The JKMRC Friday Seminars will be presented often in person, at the Indooroopilly Mine Site Lecture Theatre, and also as webinar. Registration for the webinar is required and can be made via the registration link in each seminar overview.
A large number of past webinars can be accessed on the SMI website: https://smi.uq.edu.au/webinars
