Highlights High temperature experiments demonstrated that selective sulphidation is feasible. Sulphides were submicron in size but could be physically upgraded. Nickel sulphides responded to flotation and grades of 6–8% were achieved. Low nickel grade was due to fine particle entrainment. Low nickel recovery was due to issues with …

The ultimate goal of a flotation process is to achieve the economically optimum combination of the desired mineral grade and recovery in the final concentrate from a feed of varying composition. The industrial operation of froth flotation faces many challenges, such as sudden decreases in the recovery and grade of recovered materials.
