Mineralogical factors affecting the extraction of gold in ...
There are several major factors that affect gold ore processing. Of which, gold grade, mineralogy and metallurgy are the three major ones. Technically, gold is commonly extracted from various ores using gravity, flotation, cyanidation or a combination of these processes. For refractory gold ore processing, pre-treatment technologies such as fine-grinding, …

From the perspective of metallurgical processing, gold ores can be classified into free-milling and refractory ores. Their extractive metallurgy are largely driven by mineralogical factors such as: gold particle size, association with other minerals, coatings and rimmings, presence of cyanicides, oxygen consumers and preg-robbers, presence ...

Gold extraction - Wikipedia
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting …

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 …
