The Basics of Heap Leach Pad Operation - BTL Liners

Many heap leaching irrigation liquids combine multiple lixiviants to achieve the highest possible amount of ore recovery from each pad. Lixiviants are also widely used for related mining and processing methods like in-situ mining. Irrigation, for heap leaching, often relies on modified forms of the same equipment used for watering field crops.
