Production of high value-added minerals: grain design

Select and jump to section

Overview

Particle design is a new field of science that studies the controllability of physical, physicochemical and chemical properties of particulate matter, such as shape, surface roughness, size distribution, composition, and surface characteristics. Preparation technologies used for particle design can improve the performance (e.g. solubility, reactivity, sorption, functionality) or properties (reduction of dusting, improvement of flow characteristics, anti-segregation stability, bulk density, recyclability) of materials, primarily as a result of mechanical process operations.
