Heap leaching entails placing mined ore on a large geosynthetic leach pad and pouring an acid leachate over the ore to dissolve the ore, separating targeted minerals or metals in the process. The use of geosynthetic materials prevents the contamination of the soil and groundwater by these chemical solutions and contains the valuable dissolved

Transient flow and transport in unsaturated heterogeneous

It is essential to understand how water is transported and stored in mine waste rock to predict the rates and quantities of mineral weathering products released to the environment. The lack of understanding of flow mechanisms is the largest of the difficulties facing efforts to predict waste rock leaching. A large scale (8m x 8m x 5m high) constructed waste rock pile experiment (CPE) has been

Non-rigid liners are often grouped into a category called geomembrane. Geomembranes are often used in conjunction with clay liners to form a double or triple liner combination. Seepage losses through geomembranes are estimated on the basis of flow through a hole in the geomembrane. Most synthetic liners are generally 10-9 to 10-14 cm/sec with
