Standard practices for copper in situ leaching2.1. Site selection2.1.1. General desirable characteristics. Not all deposits are amenable to intact in situ leaching. Mineralogical requirements are similar to those for conventional heap leaching: oxide copper minerals which dissolve quickly in sulfuric acid are desirable.
In 2014, more than 50 major HL-SX-EW operations worldwide recovered approx. 3 million tonnes of copper, which represents roughly 16% of total copper production. With about 327 kt produced in 2012, CODELCO's Radomiro Tomic mine is believed to takes first place in …
The resulting productive solutions were analyzed daily for copper and acid content, and the amount of sulfuric acid needed to achieve the required concentration was then added; the solution was reused for the leaching process. The product solution was fed to the extraction plant with subsequent leaching through the use of copper-less raffinate.
Heap-agitation leaching route is based on heap leaching system with an additional agitation leaching process, which can increase the copper recovery rate of low-grade ores from about 50% to over 85%. However, it would result in greater consumption of energy and material, such as electricity and sulfuric acid, and environmental impact.
It was the largest heap leaching plant in China to recover copper by the copper hydrometallurgy (L-SX-EW) at that time. In China, the output of metals extracted by the heap leaching method has increased year by year, and the great progress has been made in the ore types, heap construction, and liquid distribution of heap leaching, as …

Currently, more than 25% of copper is extracted by a heap method with the participation of micro-organisms from sulfide and mixed copper ores containing 0.2–0.5% copper in more than twenty enterprises in Chile, USA, Australia, Peru, Mexico, China, Myanmar, etc. Sulfide copper-nickel ores are leached in one large enterprise in Finland …
In the United States, for example, the energy requirement for SX/EW processing of heap or dump leaching ranges from an estimated 10 MJ/kg to 25 MJ/kg - the difference being largely the pumping costs. In the case …
1.. IntroductionHeap leaching is a widely used extraction method for low-grade minerals, including those of copper, gold, silver, and uranium. This method has new applications including nonmetallic minerals such as saltpeter (Valencia et al., 2007) and soil remediation (Hanson et al., 1993).Although a number of experimental studies have been …

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.

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.
