A leach solution is applied to the top of the ore and allowed to percolate through the heap. As the solution migrates through the ore, it leaches the gold and silver from the rock and holds it in a solution.
Gold Ore Processing: Project Development and Operations, Second Edition, brings together all the technical aspects relevant to modern gold ore processing, offering a practical perspective that is vital to the successful and responsible development, operation, and closure of any gold ore processing operation.
Understanding the time-rate-of-recovery dynamics in heap-leach operations is mandatory for analyzing the financial performance of any mining operation. It's also a must for the successful execution of a project.

Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores.
Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

Heap leaching has become a popular method of extracting gold, writes mining consultant Nicolaas C. Steenkamp and Leon Louw, writer, editor and specia - MiningFeeds
Grundfos offers transfer pumps, dosing and chemical dosing pumps, and heap leaching, submersible and end-suction pumps covering the entire mining process.
extracted. The barren solution is then reapplied to the top of the stack. Overall, gold recovery using heap leaching generally ranges from about 50 to 90 percent, although this percentage depends on many variables (Kappes, 2002; Marsden and House, 2006). Figure 1 is a simplified flow diagram of the gold heap-leach process.
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).
Heap leaching is an industrial mining process to extract precious metals, gold, copper, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials.
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
The largest copper heap leach operations are in Chile, Peru, and the southwestern United States. Although the heap leaching is a low cost-process, it normally has recovery rates of 60-70%, although there are exceptions. It is normally most profitable with low-grade ores.
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. Thirty-seven different heap leach operations with a total production of 198 tonnes of gold per year (6,150,000 ounces/yr.) were surveyed to determine operating …
Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
