摘要：

论述了碳质金矿的矿物学特性,次氯酸钠氯化法直接浸出碳质微细粒浸染型难处理金矿的工艺过程和操作条件,讨论了不同因素对浸出过程的影响,评述了水溶液氯化法浸取贵州某碳质难处理金矿的试验结果。

关键词: 碳质难处理金矿, 次氯酸钠浸出

Abstract:

A process Ieaching gold from are fractory carbonaceous gold ores with hypochlorous solution was proposed. The mineral characters of carbonaceous gold ores was briefly summarized.Cyanidation with carbon in leach (CLL) was likewise ineffective in achieving satisfactory gold extraction from these ores in the absence of any oxidative pret reatment . In the conditions under the study , over 85 % of gold was leached f rom the carbonaceous ores by hypochlorous leaching. The main factors that influenced the process rate and ext racted gold yield were tested and discussed.

Key words: refractory carbonaceous gold ore, hypochlorous leaching
