In the current economic climate, heap leaching can be an attractive and cost effective means of recovering metals, explains Terry Mandziak, Associate Consultant, SRK (US) and David Pattinson, Principal Consultant Minerals Processing, SRK Consulting (UK).
Agglomeration drums bring increased metal recovery to the copper heap leaching process.
Lessons learnt from heap leaching operations in South AmericaAn update On/Off heap leach padThese facilities use similar pads and collection systems as the permanent pad but each lift is removed after it has been leached.
The ability of the heap leaching process to recover metals amp; other materials from low grade ores will likely continue to be a tool in the mining landscape.
Mintek has developed considerable experience in heap leaching and heap bioleaching, and has undertaken an advanced research programme investigating the high temperature heap bioleaching of low grade chalcopyrite.
At first glance, heap leaching can appear to be an extremely simple technology; however, without the proper characterisation, engineering and design, a heap leach pad (HLP) can face significant issues that can affect the overall economic viability of the project. It is important that
Most mining companies favor the economic feasibility of heap leaching, considering that heap leaching is a better alternative to conventional processing (such as flotation, agitation, and vat leaching).
What is your suggestion for reduce the acid consumption in copper heap leaching? I would like reduce the acid consumption in low grade copper ores heap leaching

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.

Improvements in Copper heap leaching by use of wetting agents Proceedings of EMC 2009 3 A sprinkler system is installed on top of each heap allowing the diluted sulfuric acid to be fed uni formly over the ore. While the solution percolates through the heap, copper is leached out of the ore.
Heap leaching is one of several leaching methods.Heap leaching is, in contrast to many dump leaching operations, a pre planned process where arrangements are made to optimize conditions for leaching.
The design of heap leach pads involves a variety of components. One of the main components for these structures is the leach pad liner system, where a low permeability soil is normally used in combination
Heap leaching is a simple, low cost method of recovering precious metals from low grade ores. Ore is stacked in heaps over an impermeable leaching pad. Leach liquid is irrigated at the top; Liquid reacts with metal and dissolves it. Dissolved metal collected at the bottom in the leaching pad.
