He concluded that the size distribution from a laboratory rod mill gave a similar-shaped size distribution to that of a closed circuit laboratory ball mill. He also demonstrated how a laboratory rod mill gave a similar shape of size distribution to a 36 inch (0.8 m) Hardinge ball mill in closed circuit with a rake classifi er treating the same ore.

Whereas particle size distribution refers to the measurements of particle size for a given sample. Particle size distribution can be used to determine whether or not the particles are homogenous (size, shape, and distribution are equal). Particle size can also be used to determine if there is an excess of one particle type over another.

In particular, for a fixed ore type ground to a specified particle size distribution, increasing the dosage of any given collector from clearly being underdosed to clearly being overdosed gives an increasing value of R with dosage but also a curve of K demonstrating a maximum as a function of collector dosage. This phenomenon is shown in Figure ...
