Arsenic release through refractory gold ore processing.
Au-refractory ores, in most cases, contain elevated concentrations of arsenic, mainly with the form of arsenian pyrite (FeS 2), arsenopyrite (FeAsS), realgar (As 4 S 4), and orpiment (As 2 S 3). The entire metallurgical route of refractory ores is shown in Figure 1, while the impact of each step on arsenic exposure is described below.
