How Arsenic Affects Cyanidation Leaching of Gold
The Influence of Arsenic in the Cyanidation of Gold Ores is explained by W. B. Blyth has he is of the opinion that the presence of arsenic in an ore does not necessarily cause that ore to be refractory to cyanide treatment.He thinks the idea arose from the fact that arsenic is so often accompanied by antimony, pyrrhotite or graphite, stating that "the two former minerals cause …

Conventionally, the desired alkalinity of the gold cyanide leaching system is achieved using lime (CaO) as the pH modifier. It is not very clear how the associated high calcium concentration due to the lime and sulphate minerals act synergistically or antagonistically at high pH (~ 10.5) to influence the gold extraction rate and yield (Azizi et al., 2010; Davidson and …
