Investigating Re-grind Particle Size and Flotation Performance using Mineral Liberation Analysis
Dr Kathryn Hadler of Grinding Solutions managed a research project supported by Plymouth University investigating the impact of re-grind particle size on flotation performance. The collaborative research was presented at the Minerals Engineering International Flotation 15 conference in Cape Town.
Findings from the research were as follows:
An increase in target grind size also results in a 50% energy saving and lower fines production
This yielded a more stable froth and a higher grade and recovery than the finer grind
