IMAGING TECHNOLOGIES TO UNDERSTAND GRINDING

2013-10-25  Here an attempt is made to understand the conditions that favour fine grinding of chromite. The grinding of both gangue minerals is studied size by size. At particle scale, three parameters are addressed such as particle size, particle composition, and particle shape. The specific behavior of chromite and silicate grains is demonstrated.
