Gold process mineralogy: Objectives, techniques, and applications
The extractive metallurgy of gold is largely driven by mineralogical factors such as gold particle size; association with other minerals; coatings; presence of cyanicides, oxygen consumers, and preg-robbers; presence of refractory gold minerals; and locking of submicroscopic gold in sulfide and sulfarsenide mineral structures. Gold process …

Review of gold extraction from ores
Firstly, in highly refractory ores, the gold can be locked up in the mineral matrix so that leach reagents are unable to reach it. Secondly, in complex ores, reactive minerals in the ore can consume the leach reagents in side reactions and there may be insufficient cyanide and/or oxygen in the pulp to leach the gold.
