| 摘 要： | 根据有机质在层控矿床中普遍存在的事实，本文用柠檬酸在低温条件下对四川彭县马松岭铜矿的变质泥灰岩进行了铜的淋滤实验研究。结果发现，在低温条件下，岩石中的铜在较短的反应时间内就有较高的淋滤率，说明有机质在低温成岩成矿作用中起着很重要的作用。而且岩石中铜的淋滤率随反应时间的增长，柠檬酸浓度及反应水岩比值的增加均明显增大。

| Abstract: | According to the fact of presence of organic substances during mineralzation, we have done a experimental study on the leaching of copper from metamorphic marlite in the Masongling Copper Deposits in Pengxian County, Sichuan Province. The experiment was conducted with citric acid at low temperatures. The results indicate that the leaching rate of copper from rocks is relatively high in short reaction time and at low temperature. The leaching rate increases with the increasing reaction time and the concentration of reaction solution and the water/ rock ratio but reaction temperature that could be related to the chemical composition of the experimental rock samples. |
