Water is a key resource input to copper heap leach operations in both quality and quantity. A number of recent developments in analysis of the technology have shown that water consumption can be optimised. The leach consumption has been generally considered in terms of minimisation of the evaporative loss by changing the application method (drippers or wobblers). Modelling …

Heap Leach. A leach pad is defined as a continuously lined area which may contain one or more 'heaps'. Heaps are stacked on prepared pads to a height from 4 to 8 metres. The nominal heap height for Lady Annie Operations is 6 metres. Each heap is approximately 60 to 70 metres wide and may contain between 200,000 and 300,000 tonnes of ore.

Heap Leaching

Heap leaching is the most important method of hydrometallurgical copper extraction. Heap leaching is used for treating oxide and lower-grade secondary sulfide ores that contain up to ∼2% Cu. The ore is crushed to a uniform particle size (typically 12–50 mm), often agglomerated, and then stacked on large flat-topped heaps in a controlled manner.. Heaps are typically ∼7 m …
