Pierina Gold Mine Heap Leach Project. The Pierina Gold mine project in Peru is located at an elevation of 4,100 metres. Ausenco has been working on this project for over a decade, providing our client with innovative design solutions for the leach pad and best in class construction monitoring support services in a very challenging environment.
Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions. Modern day heap leaching, which has a relatively low level of energy consumption, is for example

Leach Pads and Ponds. The leach pad below the heap is a significant element of a heap leach design. The ideal location for the heap is a nearly flat (1% slope), featureless ground surface. Usually some earthwork is required to modify contours, but it is not necessary to eliminate all undulations.
for ore placement on the heap leach pad also determines the permeability of the pad and affects recovery. Truck dumping ore on a heap leach pad promotes compaction and effects leaching permeability and metal value inventory, Figure 3.
Leach pad and pond design We design heap-leach pads with metallurgical balance in mind, giving operators the ability to monitor pads' performance with greater accuracy. Geotechnical aspects of each facility are analyzed, including settlement and deformation, to provide a stable, long-term configuration.
The Pierina gold mine is located in the Callejón de Huaylas in the Peruvian Andes, approximately 10 kilometres directly north of Huaraz, Perú at an elevation of 4,100 metres. Surface mining began in 1998 with the ore processed by valley fill heap leaching.
This report presents a description of the magnitude and distribution of gold/silver heap leaching, the design and operation of leaching facilities, the potential for environmental impact, and management practices that can be used to minimize environmental releases.
With lessons learned from the design, construction and operation of numerous heap leach pads worldwide, SRK recommends the following for a successful heap leach facility: • Develop a site specific design that accounts for such conditions as metallurgy, topography, climate, geotechnics, environmental and closure conditions;
heap leach pad design H eap leaching has been applied to a number of different ores containing metals including gold, silver, copper, nickel, zinc and uranium. The ore can be processed as coarse rock, normally referred to as a dump leach, or as a crushed ore in a heap leach.
Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold-containing solution is leached.
