and hydrometallurgical aspects of biomining have involved the use of thin layer heaps of refractory sulfidic ores (mostly copper, but also gold-bearing material) stacked onto water-proof membranes, and solubilized...) or that it better fitted to leaching base metal concentrates and ores than to oxidizing gold concentrates. There have been a number of reports describing the microbiology of laboratory-scale column......

1 Introduction Refractory gold ores have been received much attention owing to the depletion of easily leachable gold minerals and the high price of gold. A "refractory" gold ore is an ore..., requires pretreatment such as roasting[1-2], biological oxidation[3-4] and pressure oxidation[5-7] before cyanidation[8]. Pretreatment of refractory gold ores by ozone is a better alternative......
