摘要/Abstract

摘要：

对于贫硫化物微细粒浸染型金矿石, 采用原矿碱性热压氧化预处理工艺, 其金浸出率可由常规浸出的47%提高到90%以上。从碱用量、氧化温度、氧分压、氧化时间等几方面对热压氧化预处理作业的工艺参数进行了探讨。

关键词: 碱性, 热压, 氧化

Abstract:

The gold leaching rate increased from 47% to 90% by the application of alkaline hot-Press oxidation of finely disseminated gold ore. The effects of amounts of alkali, temperature, partial pressure of oxygen, oxidation time et al. on the technology of alkaline hot-press oxidation were investigated.
