1. Introduction. Cyanide leaching has been the predominant process for gold extraction from mineral resources for more than a century (Hilson and Monhemius, 2006, Li et al., 2012b, Örgül and Atalay, 2002).The major reasons for the acceptance of cyanide over the other lixiviants include higher chemical stability, lower cost and better understood chemistry (OforiSarpong and OsseoAsare, 2013).

Leaching gold ores with non toxic methods

I recently tested the EcoGoldex product (Os series) on a lab scale with promising results. It was a sulfide gold ore with 30% silver from a friend's mine. He wants to scale up the process to leach whole ore in vats or tanks but it requires a finer grinding method (ball mill) to replace the Chilean mill he has now.

Factor affecting gold leaching: leaching time. Gold cyanide leaching is a relatively slow process, the leaching time is over 24 hours generally,and the gold leaching rate is improved with the extension of leaching time, but the gold leaching speed is reduced corresponding, and finally the gold leaching rate tends to a limit value.

Leaching is the process by which constituents of a solid material are released into a contacting water phase. Although some species may be more of an environmental concern than others, the leaching process is indiscriminant such that all constituents (, major or minor matrix components as well as inorganic, organic and radionuclide contaminants) are released under a common set of chemical ...
