These ore types require a pre-treatment before undergoing a typical processing circuit Comminution Processes. Comminution is the process where ore particles are liberated from gangue material through progressive size reduction …


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 ...

gold orEs and MinErals gold orE tyPEs Gold ores are commonly classified by the metallurgist into two major categories: free-milling and refractory ores. Typically, free-milling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores are defined as those that give low gold recoveries or ...


In the dressing production, due to the different types and nature of gold ore beneficiation methods used are also different, but commonly use re-election, flotation, amalgamation, cyanidation and resin slurry method, CIP adsorption, and new heap leaching gold extraction process. For certain types of ore, always using joint gold extraction process.

Cyanide leaching process is one of the common gold ore beneficiation processes. The process index depends on factors such as gold particle size, sulfide content, ore block size, leaching speed, leaching time, cyanide concentration and leaching slag washing degree. The factors that affect gold leaching include grinding fineness, pH, temperature, cyanide dosage, …


(2) Carbonaceous gold deposit. This kind of gold ore contains a certain amount of organic carbon and inorganic carbon. When extracting gold, in addition to the cyanidation process of gold into the solution, there is also the "gold robbing effect" caused by the adsorption of gold cyanide complexes in the solution by carbon substances, which makes the leached gold return to the …


Gold ores are classified "free-milling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an …
