Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the effect of stirred and ball mill grinding on the particle shape of GCC by dynamic image analysis (DIA) is still lacking in the literature. Therefore, the aim of this study is to ...

Introduction. As coarse grained, easily processed ore bodies are depleted, more disseminated, finegrained ores are being treated. Adequate liberation of valuable components within a finegrained ore is often only achieved once the particle size of the ore has been reduced to levels below the traditional ball mill cutoff of 45. μm.. To aid in the economic liberation of finegrained minerals ...
