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 1–4 raw …

Carbon–arsenic-bearing gold ore is a typical complex refractory gold resource. Traditionally, xanthate was often used as a flotation agent to separate gold minerals. But, in this paper, in order to reduce the cost of the agent, kerosene was used as an auxiliary collector, and the gold grade and recovery rate were increased by about 10 …

The gold particles of ALRG gold ore are almost wrapped by pyrite and arsenopyrite, and the direct gold leaching extent is less than 40 %, making it an extremely refractory gold ore. The ore sample in this study has an extremely low gold content of 0.85 g·t −1, iron content of 3.21 %, sulfur content of 2.27 %, and arsenic content of 0.19 %.
