通过试验研究，提出了利用难处理矿石的热压氧化预处理的原有体系直接进行氰化提金的新工艺。
This paper makes use the original system of pretreating refractory ore by hot-press oxidation to extract gold by cyanide process.
采用酸性热压氧化工艺对某难处理金精矿进行预处理，其金回收率可由常规浸出的35.6%提高到94.3%。
With acid hot-pressure oxidation pretreatment, the gold recovery rate of a certain refractory gold concentrate is raised from 35.6% to 94.3%, comparing to the ordinary leaching process.
