The design of liner systems for heap leach pads is a delicate balance between grading (earthworks), selection and testing of geosynthetic materials, selection and testing of liner bedding and overliner materials. In addition, the liner system design must address operational and environmental conditions that may be applied to the heap.
During the design phase, potential processing routes are identified and evaluated to optimise gold beneficiation of the particular gold bearing ore. Modular plants offer a complete solution from run-of- mine (ROM) reception, primary and secondary crushing, milling, gravity concentration when appropriate, flotation when appropriate and ...
The most preferred pad liner system in current heap leach practice is the composite liner with an overlying drain cover fill (Breitenbach 1999). The primary purpose of the composite pad liner design is to prevent the loss of pad and pond process solutions from the lined facilities for both economic and environmental reasons.
ROM Wall and Bin. The ROM retaining wall utilises a Reinforced Earth (RE) design solution. This design approach has the benefit of requiring only simple and small concrete strip foundations.
