Establishing thE ProcEss MinEralogy of gold orEs

Process mineralogy can play an important role in optimizing the metallurgical processing of gold ores. It is widely used to characterize gold in gold ores and mill products, and to determine the mineralogical problem(s) causing gold losses. The information acquired from a process mineralogical study can be used as a basis for a metallurgical testwork program for process design or optimization. Ideally, a process mineralogical study should be conducted prior to the start or at the early stage of a metallurgical

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,

Gold & complex ores Research with ZEISSZEISS

Gold deposits can display mineralogical and textural variability that serve to add complexity to the recovery process. The intricate nature of an ore, regardless of whether the gold is refractory or free milling, can be explained in terms of the variability of the Au-bearing phases, the granulometry and the ore’s modal mineralogy (Goodall and Scales. 2007).
