Defining P50 and P80 Manual - Finance
2019-11-8 Defining P50 and P80 2 UNCLASSIFIED Defining P50 / P80 P50 and P80 refer to a confidence level regarding the probability of the cost not being exceeded, and does not indicate a quantum of cost or proximity to the actual cost realised. That is, P80 is not a cost plus/minus 20% but instead it is a cost that will not be exceeded 80% of the time.

Particle Sizes - Rota Mining
Particle size plays an important role in many industries and applications since it influences many properties of particulate materials. It is a valuable indicator of quality and performance. In mining, there are generally three values to define powders in terms of micron size: Dv10, Dv50, and Dv90. Simply, these values respectively represent 10 ...

Analysis of Particle Size Distribution in Dump Leaching ...
2017-1-1 In this study, we investigated the particle size distribution in dump leaching by using image analysis technique. The results showed that the particles in the dump varied from smaller than 2 cm to larger than 200 cm in diameter. P80 was calculated to be 200 cm, which was significantly higher than the historical data used by the operation.
