在 ２５～５５℃低温条件下研究了苹果酸对广东云浮含铊黄铁矿的准动态淋滤，模拟考察了Ｔｌ、Ｃｄ和 Ｐｂ三种有毒元素随矿山开采和环境介质等因素作用而进入环境的情况。结果表明，云浮矿中ＴＩ的含量大大超过地壳背景值，越细的粒级中含量越高。从淋滤结果可以推测，在矿山开采过程中，在环境介质的淋滤作用下，Ｔ１进入环境的速率远比Ｃｄ和Ｐｂ快。在介质浓度、作用时间和温度等影响淋滤结果诸因素中，温度的影响尤为明显。
The quasi-dynamic leaching of malic acid to thallium-rich pyrite in Yunfu was studied at low temperature of 25-55 ℃. The three toxic elements of Tl, Cd and Pb were investigated to enter the environment with the mining and environmental media Case. The results show that the content of TI in Yunfu ore greatly exceeds the background value of the crust, and the finer the content is, the higher the content is. It can be inferred from the leaching results that during the mining process, the rate of T1 entry into the environment is much faster than that of Cd and Pb under leaching of environmental media. In the medium concentration, duration and temperature affect the leaching results and other factors, the impact of temperature is particularly evident.
