Ore Sorting in Mining
Sorting only effective within certain particle size ranges: Too fine, and the throughput decreases Throughput decreases with particle size +10mm is typical lower economic limit Too coarse, and dilution increases Upper size determined by ore characteristics and sensor e.g. 40 - 50mm is average penetration depth of XRT Generally less than 100mm

Particle Size Distribution Effects that Should be Considered …
It’s therefore important when using geometallurgical testing to compare floatability of different ore types, or to predict the performance in full-scale plants, or to assess optimum plant grind size, that the characteristics of the particle size distribution produced in laboratory grinding be as similar to that of the plant as possible.
