Gold Process Mineralogy SGS. Process mineralogy is often used to predict the response of a gold ore to the various candidate process. In addition, during the processing of a gold ore, periodic mineralogical analyses of ore feed and mill products are needed to determine the nature of the problem if the gold recovery is lower than expected.

Refractory Gold. The last type of gold deposit is called refractory gold, and it is the most difficult type to extract. It can be defined as any ore that responds poorly to a conventional gravitycyanidation process with examples including copper porphyry, complex sulfides, arsenopyrite and leadzinc associations.
