  • Deportment of gold in an autoclave pressure oxidation AC

    Request for analysis: A carbonaceous refractory sulphide ore is processed in an autoclave and subsequently subjected to a cyanide leaching. An initial mineralogical study of the feed ore by quantitative dynamic SIMS analysis has shown that 95% of the is contained as sub-microscopic in pyrite with the remainder contained in

  • Gold extraction

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

  • Polymetal to expand pressure oxidation gold treatment in

    was selected as the most feasible processing technology for double refractory ores. It is able to achieve recoveries of 96% by utilising high temperatures, elevated and oxygen to recover encapsulated while conventional cyanidation methods would result in sub-optimal recovery rates of 20-40%

  • PDF Conditions and Design Considerations for Maximising

    However, extraction from roasted ores carried out on laboratory scale equipment often invariably yields lower recoveries than other processes such as bio- or

  • Redox potential measurement during pressure oxidation POX

    Pressure oxidation POX leaching has been commercially applied to refractory gold ores since the 1980s. In the process, sulphide material is oxidised and dissolved in order to release the gold encapsulated in the sulphide matrix, making the gold available for further recovery
