利用淋溶实验，研究了乐昌铅锌尾矿的酸化及其对重金属溶出的影响。结果表明：高硫和中硫尾矿因含很高的有效硫（分别为２０．４％和１５．９％），在尾矿的堆放过程中会发生酸化，发生酸化的时间在第５１周左右，低硫尾矿（有效硫为７．２％）在短期内不会发生酸化。尾矿发生酸化后，将促进其中盐份的溶解，从而使得Ｐｂ、Ｚｎ和Ｃｕ等重金属的溶出增高。本研究可为铅锌尾矿的环境管理提供科学依据
Using leaching experiment, the acidification of Lechang lead-zinc tailings and its effect on the leaching of heavy metals were studied. The results show that high sulfur and medium sulfur tailings, due to their high available sulfur (20.4% and 15.9% respectively), are acidified during the tailing deposit and the time for acidification is 51 weeks Around, low-sulfur tailings (effective sulfur 7.2%) will not occur in the short term acidification. Acidification of the tailings, which will promote the dissolution of the salt therein, so that the dissolution of heavy metals such as Pb, Zn and Cu increased. This study can provide a scientific basis for environmental management of lead-zinc tailings
