摘要
利用不同成分的浸取母液在温度550—250℃(间隔100℃)、压力800×10~5Pa条件下,分别对变质岩样品(含金240ppb)进行浸滤实验。实验表明,岩石中金在各种浸液中都有不同程度的迁出,淋滤迁出率最高可达28％。本文利用实验结果,对金在热水溶液中的迁移形式等作了探讨。
Leaching experiments on samples of metamorphic rocks in leaching liquors of different compositions at temperatures from 550 to 250℃ (intervals 100℃) and pressure of 800×10~5 Pa have been made. The abundance of gold in the samples is 240 ppb, The results of experiments showed that gold has been removed from rocks to a certain extent. The highest rate of leaching is 28％. The form of removal of gold in hydrothermal solutions is discussed using the experimental results in the paper.
