 ·  · Today, the use of activated carbon in conjunction with heap leaching is a simple, economical process that is suitable for exploiting lean resources or small ore bodies. The capital investment for this process is estimated to be about 20 to 25 pct of the cost of a conventional countercurrent decantation cyanide plant, and operating costs are about 40 pct of a conventional .

Alternative Processes

Heap Leaching: Heap leaching is a process used in mining operations in order to separate the desired metal substituents from crushed raw ore. In this process chemicals are used to dissolve the metal ions from the run of the mine into a solution where they are recovered through further chemical processing techniques (Zanback).

Precious Metal Heap Leach Design and Practice

Precious Metal Heap Leach Design and Practice

Precious Metal Heap Leach Design and Practice Daniel W. Kappes1 ABSTRACT Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods.

Heap leaching

 · Although the heap leaching is a low cost process, it normally has recovery rates of 6070%, although there are exceptions. It is normally most profitable when used on lowgrade ores. (Highergrade ores are usually put through more complex milling processes where higher grades x higher recoveries = higher profits.

How Heap Leach Pads Compare to Other Mining and Processing ...

Heap leaching only needs gravity and lowcost irrigation equipment to achieve the same results, albeit at slightly slower efficiency levels. Vats are far more limited in size than heap pads, making it easier to extend the processing volume of a mine with pads than vats.

What is Heap Leaching? (with picture)

What is Heap Leaching? (with picture)

The heap leaching process is used to extract metals such as gold, copper, and nickel and may be used on low grade ores and mining tailings which are generally considered to be of no commercial value. The process also produces yellowcake, a concentrate leached from uranium ore used in the production of nuclear reactor fuel.

Heap Leaching Basics

Heap Leaching Basics

Heap leaching is a process through which metals are extracted from the ore in which they are found. Heap leaching is often chosen for its efficiency and costeffectiveness. As the need for resources increase, the heap leaching industry has risen to the occasion with advancements creating an even more efficient leach.

Assessing a twostage heap leaching process for Platreef ...

 · A twostage heap leaching process is proposed for the lower grade materials, which can run parallel to the conventional processing route of concentrating–smelting–refining. This method is proposed for appliion as a twostage heap leach for lowgrade whole ore and concentrate, and possibly as a combined heap and tank leach for lowgrade concentrate.
