Geotechnical engineering for heap leach operators Krishna P. Sinha, KPS and Associates, USA Mark E. Smith, Brazilian Nickel Ltd, USA Omar Y. Caceres, Brazilian Nickel Ltd, USA Abstract The authors present a geotechnical primer especially oriented to heap leach operators, as well as geotechnical engineers new to heap leaching.
The heap leaching process entails the breaking (crushing) of ore, placing the crushed ore into lifts, application and collection of a leaching solution, and then processing the solution to recover the metals. This course provides a comprehensive introduction to all aspects of heap leach design, including ... Design Criteria and Metallurgical ...
Heap Leach – our associates have performed preliminary to final design, stability analysis, stacking plans, and leaching plans for many heap leach projects. To-date we have completed over 30 heap leach designs including locations such as Alaska, Arizona, Nevada, Mexico, Arizona, Turkey, Armenia, Ghana, Chile and Peru.
Heap leaching is an industrial mining method to dig out precious metals and copper compounds from ore. Process of heap leaching. The mined ore is crushed into tiny chunks and heaped on an impermeable plastic and/or clay lined leach pad where it may be irrigated with a leach solution to melt the valuable metals.
At first glance, heap leaching can appear an extremely simple technology; however, without proper characterisation, engineering and design, heap leaching faces significant issues that can affect the overall economic viability of the project.
Heap Leach - Courses and Live Webcasts. Online courses, short courses and live webcasts about Heap Leach for mining and geoscience from Edumine.
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
The application of cyanide heap leaching has grown in recent years and this trend is expected to continue. Operating Practices. Heap leach operations involve the use ot liners and specially constructed leach pads and solution ponds. The basic design and operational layout of heap leach projects are very similar at all facilities.
Estimated Water Requirements for Gold Heap-Leach Operations By Donald I. Bleiwas Introduction This report provides a perspective on the amount of water necessary for conventional gold heap-leach operations. Water is required for drilling and dust suppression during mining, for
Design and supply of an agglomeration plant, overland conveyor with mobile tripper, and mobile stacking equipment, including twenty 48" x 125' portable conveyors, a 90' Horizontal Feed, 140' Horizontal Conveyor and a 120/140' Radial Stacker, for a 1,700 t/h gold heap leach operation.
Heap leach pad design in regions where terrain characteristics are particularly aggressive is carried out using the valley fill method. In Peru, most heap leach pad facilities are designed and constructed with the valley fill method; many of these facilities are in very aggressive terrain. Valley fill heap leach pads have
PDF | This paper presents a design and construction review of a heap leach pad located in northern Peru, based on several aspects of interest that have been observed and should be taken into ...
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.
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. It is only
performance under load the design of the overliner materials must be compatible with the geomembrane liner and the solution collection/air injection piping. This paper presents a discussion on the design of liner systems for heap leach facilities. The primary focus of this paper is the development of a design that considers the behavior and

Redesigning what is possible in heap leach equipment technology. Having 25 years' experience with a history of partnering with clients to create solutions focused results in even the harshest or most remote locations, we have extensive experience from feasibility studies through to design, engineering, project delivery, commissioning and operations.
Ore placement and solution management greatly influence the design and layout of earthworks for a heap leach facility. At SRK Consulting, our approach is to assess and optimise earthwork and lining requirements based on the topographical and geotechnical characteristics of the site, the engineering characteristics of the ore, and the environmental objectives for the project.
