2015-12-16  with the use of significantly more reagents or more complex pre-treatment processes. 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 ores and oxidized ores are free-milling and gold

2020-3-19  Gold and copper containing ore mining process. The difference between this kind of gold ore and the third kind of gold ore is that gold has a low grade, but can be used as one of the main comprehensive utilization elements. The natural gold in the ore is medium size and the symbiotic relationship between gold and other minerals is complex.

Cyanide Process - Gold Cyanidation Process Gold

Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions form a complex ion with the molecules of gold. The cyanide process is as explained below-The ore is grounded and crushed.

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).
