Heap Leach Application
Heap leaching is the preferred route for low-grade gold oxide ores (0.3-1.5 g/t Au) where conventional milling is not economically viable.
Heap Leach Pad Design
Pads require engineered foundations with double composite liners (clay + HDPE geomembrane). Ore preparation (crushing, agglomeration) improves permeability for clay-bearing ores.
Solution Management
Pregnant leach solution (PLS) is collected and routed to gold recovery (ADR plant). Barren solution is re-circulated with cyanide make-up.
