Based on the mineralogical characteristics and mineral processing techniques required, gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below Placers, quartz vein gold ores and oxidized ores Generally, placers, quartz vein gold.
