摘　　要：通过室内试验与数值模拟对方柱浸铜过程中溶质运移的规律进行了研究.柱浸试验以含铜品位1.25%的羊拉铜矿2.372 kg为例,在截面为6×6 cm2高60 cm(实际装矿高度为48 cm)的方形浸出柱内经过28 d浸出.试验过程中对Cu浸出率进行了测量,同时运用Eviews和Matlab软件进行Cu浸出率变化趋势的拟合.A square column leaching experiment was designed to probe the feasibility of simulating heap bioleaehing with drip irrigation system. 2. 372 kilogram of Yangla＇ s copper ore with a copper grade of 1.25 % was loaded in a 6 × 6 cm2 column whose height is 60 cm. A 28 - day leaching experiment was conducted. Leaching rates were measured during the process, and the data were dealt with by Eviews and Matlab.
