The process mineralogy of gold The classification of ore
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

6-Characterization of the Gold Ore to Acquire an
· In this study the conditions of gold ore deposits have a thin thickness (vein). These gold ore deposits have an economic value if they are developed by traditional gold mining. The objective of the research is to identify and characterize gold ore as well as to analyze the optimum condition to obtain the perfect gold mineral liberation degree.

· Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 of the gold under the condition that the ore size is 80 < 75 µm (Joe Zhou 2004). Complex ores meanwhile require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy 1994).
