Many gold deposits are sulphidic in nature and contain gold in a form that is inaccessible to lixiviants. Refractory gold ores often contain finely disseminated gold particles encapsulated by a sulphide mineral matrix containing arsenopyrite, pyrite and pyrrhotite (Bosecker, 1997).The inaccessibility of gold to lixiviant has been overcome by biooxidising the …

Abstract. Artisanal and small-scale mining (ASM) takes place under extreme conditions with a lack of occupational health and safety. As the demand for metals is increasing due in part to their extensive use in 'green technologies' for climate change mitigation, the negative environmental and occupational consequences of mining practices are disproportionately felt in low- and …
