Heap Leach Copper Ore Max Plant Project

Heap leaching amp; SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution sulphuric acid over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.

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.

Advances in high-temperature heap leaching of refractory

operation of the heap leaching process also increases. The heap leaching of copper ores is an example of such a trend, where heap leaching was initially applied only to the acid leaching of oxide ores. The most important factors to be considered in oxide heap leaching are the copper dissolution, acid consumption, and gangue chemistry. The rate at which acid can be supplied

The solution discharging from the heaps, pregnant leach solution (PLS) will vary in copper concentration over the life of the heap, initial grades may be as high as 50 g/L of copper. Heap leaching technicians might only get PLS grades only fractionally greater than the raffinate irrigated after raffinate has been circulated a number of times.

Sulfuric acid injection in copper heap leaching - LEWA

The leaching reagent (dilute sulfuric acid) is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting solution of sulfuric acid and copper sulfate is collected in a small pool. Copper concentration is around 65%. Next step is solvent extraction.
