The pretreatment of refractory gold ore is a complex chemical process. In addition to the oxidation of pyrite, some side reactions also occur. The phase changes of refractory gold ore before and after pretreatment are shown in Fig. 11. The main phases of refractory gold ore include quartz (SiO 2), pyrite (FeS 2), and dolomite (CaMg(CO 3) 2 ...

Gold ore is a rare mineral block found underground. Deepslate gold ore is a variant of gold ore that can generate in deepslate and tuff. Gold ore drops as raw gold if mined by an iron pickaxe or higher. If mined by any other tool, it drops nothing. Mining with a Silk Touch pickaxe drops itself. It is affected by Fortune enchantment, dropping 1–2, 1–3, or …

The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold …
