| 摘 要： | 铜矿石从坑下采出后，硫酸铜仍继续不断生成，其生成量与矿石自然堆放时间及黄铁矿含量成正比关系，矿石粒度愈细硫酸铜的生成速度愈快，矿石中硫酸铜生成速度最快的时间是矿石采出后的头五天，硫酸铜主要由次主硫化铜氧化而成。

| Abstract: | Cupric sulfate is continuously formed after copper ore is mined out from gallery.The content of cupric sulfate is directly proportional to content of pyrite in ore and the time of natually stockpiling of ore.The fi-ner the particle size of ore,the faster the formation spedof cupric sulfate.The first five days after ore is mined is the time period of the fastest forma-tion speed of cupric sulfate in the ore.Cupric sulfate is mainly formed by oxidation of secondary cupric sulfide. |

| Keywords: | Oxidation of copper ore Cupric sulfate Pyrite |
