Traditional milling methods (e.g. LM2 bowl and disc pulveriser) are ineffective at reducing the grain size of gold particles. This issue has led to the widespread belief that only synthetic materials or gold ores containing fine grained and homogenously distributed mineralisation can be used to make CRMs. Figure 1.

The gold content in the ore, calculated from the balance of experiments, is 2.71 g/t (test No. 1) and 2.11 g/t (test no. 2). To determine the granulometric characteristics of the material and the distribution of gold by size classes, a sieve analysis of crushed ore was carried out for a material size of − 5 mm.
