Investigation of the link between the shapes of particles and the separation of Wollastonite from the Pyroxene Group Minerals
This research investigates how particle morphology impacts the efficiency of gravity and magnetic separation when refining wollastonite from pyroxene minerals. While industrial purification typically relies on chemical flotation, this study demonstrates that reagent-free physical methods can achieve high-purity concentrates by exploiting the mineral's unique needle-like shape. Quantitative analysis reveals that elongated particles preferentially report to light and non-magnetic fractions, while more rounded, equant particles concentrate in heavy and magnetic products. The findings suggest that shape-controlled grinding is a vital strategy for improving mineral selectivity in ceramic and glass applications. Ultimately, the research highlights that particle geometry acts as a decisive factor alongside density and magnetic susceptibility in governing separation outcomes.
