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.

Nuton: A better way to produce copper

At Nuton's core is a biological leach process that transforms copper-bearing rock or mine waste into 99% pure copper cathode. Our leaching process starts by creating a heap – a very large pile of crushed rock. Depending on the site, that could be newly mined ore or previously mined rock that has been discarded as waste.

Deconstructing the Leaching Ratio | Mining, Metallurgy & Exploration

The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of annual copper production over the past 10 years. This level of production has been achieved through and supported by …

Heap leaching explained

In 2011 leaching, both heap leaching and in-situ leaching, produced 3.4 million metric tons of copper, 22 percent of world production. The largest copper heap leach operations are in Chile, Peru, and the southwestern United States. Although heap leaching is a low cost-process, it normally has recovery rates of 60-70%.

Precious Metal Heap Leach Design and Practice

Comsur's Comco silver heap leach at Potosi, Bolivia, showed the same recovery in both a heap and an agitated leach plant. However, the silver ore leached very slowly and residence time of up to 4 days was needed in an agitated leach plant. Although the heap leach took several months to achieve the same recovery, the economics favored the heap.
