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 Process Mineralogy - SGS

Process mineralogy is often used to predict the response of a gold ore to the various candidate process. In addition, during the processing of a gold ore, periodic mineralogical analyses of ore feed and mill products are needed to determine the nature of the problem if the gold recovery is lower than expected.

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 of refractory gold minerals and

Mineralogical investigation of gold ores - ScienceDirect

01.01.2005  Ore mineralogy in general and more specifically the process mineralogy of gold is one of the criteria used for selecting the most appropriate pretreatment option. Carbonate minerals need to be removed prior to pressure oxidation or bioleaching, and this is often achieved in a sulfuric acid pre-oxidation step. Finely disseminated submicron gold-bearing pyrite and

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, pretreatment technologies, such as fine-grinding, autoclaving,

The leaching and adsorption behaviour of gold ores

There are many non-idealities in gold processing which are becoming increasingly important as simple free-milling oxide ores are depleted. During cyanidation and adsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling

Gold Extraction Recovery Processes

29.02.2016  The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is 0.8-1.1 g/t. The leaching solution is spread at the top of the pile and the pregnant solution will have to percolate through the pile. The design considers special
