copper production plant by heap leaching:

Heap leaching - Wikipedia

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. mo

A Brief Note on the Heap Leaching Technologies for the ...

Originally, heap leaching was practiced 500 years ago. Georgius Agricola published a book De Re Metallica in 1557 and reported that the heap leaching process was finished in a 40-day cycle [1]. Since the middle of the 16th century, heap leaching was practiced in Hungary for copper extraction.

Zaldívar Copper Mine - Northern Chile - Mining Technology ...

Heap leaching of ore uses dynamic stacking in 6m lifts and chemical and bacteriological dissolution of copper through consecutive lifts from the top to the bottom of the heap. Copper is recovered from the oxides by sulphuric acid in the circulating leach solutions, and from sulphides by bio-leaching using bacteria naturally present in the ore.

Recovery of Copper by Solution Mining Methods

Supplementing production from conventional heap leach operation, the in-place rubble leaching project at Silver Bell is estimated to recover 20 to 25% of the contained copper. The relatively low recovery achieved by this method is most likely due to the presence of insoluble hypogene copper sulfides, inadequate contact of the leach solutions
