Mineralogical investigation is a critical and integral aspect of gold project development and process optimization. The process mineralogy of gold is not limited to the gold minerals, submicroscopic gold, and their carriers but also includes the study of gangue minerals and other species that may affect gold processing, such as cyanicides.

The first stage in the processing involves crushing and grinding the ore to liberate the gold particles. This involves: Crushing: The ore is crushed into smaller pieces using crushers. Grinding: The crushed ore is then ground into a fine powder using ball mills or other grinding equipment. ( A crusher and a ball mill )

Stage 3: hashing. The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation …

Low-grade gold ore: If the gold ore has a low grade, that is, the metal content is low, the gold concentrate obtained after processing will be correspondingly low. This means that the gold concentrate contains less metal, and the recovery rate of gold and the efficiency of gold smelting will be reduced accordingly.

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for …

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked ...

The practice of gold minerals beneficiation is optimized by using the information obtained from applied mineralogy. In this way, at the moment of development and select a process for treatment a gold ore, try to identify the gold minerals is the first step. Obviously, the detection of non-valuable minerals is important.
