The size distribution of the diamonds in a kimberlitic rock is a negative exponential function—i.e., the frequency of large diamonds diminishes exponentially with increasing size. The number of microdiamonds in narrow fine sizes allows predicting the probability of discovering coarser valuable diamonds. For deposit evaluation, the microdiamonds are recovered in the solid residue of the leaching of some hundreds kilograms of rock samples.

Abstract
The size distribution of the diamonds in a kimberlitic rock is a negative exponential function—i.e., the frequency of large diamonds diminishes exponentially with increasing size. The number of microdiamonds in narrow fine sizes allows predicting the probability of discovering coarser valuable diamonds. For deposit evaluation, the microdiamonds are recovered in the solid residue of the leaching of some hundreds kilograms of rock samples.File in questo prodotto:
