If you have more rock (unless the sample is really huge, 2 kg or better), crush the entire sample. The crushing yield is very dependent on rock type and operator skill -- getting it right requires some experimentation as described below. A good rule of thumb is that a sample about the size of a softball will yield more than enough material.

A reduction in particle size is accomplished by crushing and grinding the gross sample. The resulting particulates are then thoroughly mixed and divided into subsamples of smaller mass. This process seldom occurs in a single step. Instead, subsamples are cycled through the process several times until a final laboratory sample is obtained.

A sub-sample from the first sample of every batch is screened after both crushing and pulverising so that equipment and time processed can be adjusted to produce the desired particle size. A minimum of one in every 50 samples after that is checked to be sure samples continue to pass the criteria for the method selected.
