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.

Treatment for gold ores with high content of carbonaceous matter …
The refractoriness of gold ores occurs by occlusion or entrapment of subatomic gold particles in matrices of sulfide minerals (pyrite, arsenopyrite, stibnite, etc.) and insoluble siliceous gangue, by association with tellurides, clays and carbonaceous matter [].The carbonaceous material can adsorb gold, an effect known as preg-robbing, from the solution similar to …
