| 摘 要： | 某些金精粉中单体金和裸露金所占比例虽然较高，但采用常规氰化法直接浸取时，金的浸出率仍然很低。这种金精粉经微爆处理后，由于组成矿物的特性发生了一系列的变化，加之脱除了残留在矿粒表面的浮选药剂，金的浸出率可得到大幅度的提高。

| Abstract: | The detailed investigation has shown that although gold concentrate powders have a higher proportion of liberated or exposed gold particles, the results obtained by direct leaching them using conventional cyanide process are not very satisfactory. After microcrack treatment, their leaching rate can be notably increased with decrease of the content of freely soluble copper and removal of flotation reagent on mineral surfaces. |

| Keywords: | microcrack technology gold mineral freely soulble copper flotation reagent leaching rate |
