Particle Sizing Iron Ores

Particle size and shape are important parameters that can significantly affect mineral processing plants and pelletizing plant performances (Brozek and Surowiak, 2007). For example, using finer particles (with a certain size) in magnetic separation could improve the iron grade. The shape of crushed ore affects the product particle size in a
