Theoretically, two particle packing models occur, that is, loosening and wall effects, with different particle sizes, by bimodal particle size distribution systems. 26 - 28 The loosening effect occurs when the coarse spherical graphite is dominant, and the fine spherical graphite is not sufficiently small to fit into the voids along with the coarse spherical graphite without distorting the skeleton of the coarse particles.

Particle Analysis in Mining and Minerals

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

In contrast, the results for NPFeed5%C and NPFl75%C obtained by MLA show a somewhat coarser particle size distribution in comparison to the two other methods (Table 3). This is tentatively attributed to minor preferred orientation of the graphite flakes into the polished sample surface, an effect that may be particularly pronounced for graphite- rich samples.
