In recent years, the interest in adjusting the grinding conditions followed an increasing trend due to the finer liberation sizes of valuable minerals. In this context, many parameters such as grinding type (wet or dry), medium, time, etc., are extensively considered to determine the optimum conditions of grinding not only for the target size but also for other physical properties of particles like their shape. In this manner, although the contribution of different grinding media like ball, rod, or autogenous) were previously reported in literature for different types of minerals, there are a few studies conducted for the effect of grinding time, in terms of its contribution to shape and related flotation kinetics constants for a low-grade magnetite ore sample. In this study, a laboratory-scale ball mill running under constant conditions was used to examine the link between grinding duration, particle shape, and flotation kinetics of a low-grade magnetite ore. Particle shape was measured using both dynamic and classical image analysis methods, and a narrow particle size fraction was chosen to reduce size effects. A first-order kinetic model was used to assess flotation kinetics, and statistical analyses were used to measure correlations between flotation rate constants and particle shape descriptors. Overall, the study's findings showed that the floatability of low-quality magnetite particles can be improved by modifying their shape through adjusting the grinding time.
