Sequential pretreatment of double refractory gold ore …

 · The type of ores, in order of increasing difficulty, are alluvial ores, free milling ores and refractory ores (Lunt and Weeks, 2016). Currently, refractory gold ores make up about one-third of the total gold production from natural ores, and they typically yield about <50% of gold in average during direct cyanidation regardless of gold grade ( Ofori-Sarpong et al., 2013, Yang et al., 2013 ).

As such, the ores formed near crustal rocks characterized by high U/Pb ratios, i.e., high µ ( 238 U/ 204 Pb) values. Alternatively, the magmas that formed the host rocks and that furnished Pb to the mineralizing fluid have crustal sources older than those cropping out in the Tapajós Gold Province today and have inherited Pb isotope compositions from these sources.
