Process Flowsheet Selection ScienceDirect. While refractory characteristics can be seen in a variety of ore types, including auriferous base metals and rocks with a high carbon content, the major focus in refractory gold processing has been on goldbearing iron sulfides, such as pyrite, arsenopyrite, pyrrhotite, telluride, stibnite, and, most recently, the sulfosalts, particularly enargite ...
I will say that from my understanding, many seem to agree that in sulfide gold ores, the occurrence of gold appears to occur as a replacement of other minerals, possibly iron. One USBM paper summed up five noticeable characteristics of auriferous pyritic ores. The gold occurs as tiny flakes on the crystallographic planes of the pyrite.
Abstract. GENCOR Ltd. has pioneered the commercialization of biooxidation of refractory gold ores. Development of the BIOX ® process started in the late 197os at GENCOR Process Research, in Johannesburg, South Africa. The early work was championed by Eric LiveseyGoldblatt, the manager of GENCOR Process Research who directed pioneering and innovative research into bacterial oxidation .
The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation ...
WHAT''S HAPPENING IN GOLD ORE PROCESSING? April 2019 . Factors driving new developments in gold technology include increasing environmental concern and government regulation over the use of cyanide, the trend towards refractory, complex, and lower grade resources, and the pressure to reduce operating cost and increase plant performance efficiency.

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately gram per tonne gold and per cent copper.
available for the extraction of gold metal from its ores. Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. This process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen. For refractory ores such as
