Typically leach pads are made by grading the surface with a slight down slope, or if an operation is limited in area the natural contours of the adjacent ridges will be used in what is called a “valley fill” leach pads. In both cases the base of the pads

Heap leaching - Wikipedia

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. mo…Solution Mining - an overview | ScienceDirect Topics,For heap leaching, the mined ore is subjected to size reduction by crushing before stacking on impermeable under liner fitted pads. If the ore is very permeable, little or no crushing may be required, Lixiviant contact with the mineral particles needs to be ensured through efficient percolation. Percolation rate should be slow enough to facilitate necessary contact periods between the ore particles and the lixiviant. Uniform permeability is essential to ensure optimal flow of leach solutions,crushing for heap leaching solution mining,How Heap Leaching Works. As seen in the flow chart below (figure 1), the ore, after being removed from the ground, is crushed down into fine particles. Traditionally, the fine particles would typically go from crushing straight to a heap, where leaching solution would
