Heap leaching is great for big low grade ore bodies you have the exact opposite. Your recovery will be on the lower end of the above, and if you are in an area with high rainfall things can get very interesting.
Nov 12, 20150183;32;HEAP LEACHING OF GOLD amp; SILVER ORES Heap leaching is the process to extract precious metals like gold, silver, copper etc, from their ore by placing them on
Process Introduction Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from lowgrade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the goldcontaining solution is leached.

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of lowgrade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap
The crushed ore undergoes an agglomeration stage, after which the agglomerated ore is deposited onto the heap leach pad. The heaped ore is irrigated with a lixiviant (a liquid medium) to dissolve the metals and generate the leachate. For Breton Scott, managing director of Bowline Professional Services, the most important advantage of heap
Feb 09, 20160183;32;Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then reseparates them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore

This ore shows heap leach recovery of only 10 to 15% and is not suitable for heap leaching. Because of the different ore types, the northern Nevada operations (for instance, Barrick's Goldstrike Mine) may employ .
Gold Mining Process Development . THE BASIC PROCESSES OF GOLD RECOVERY antimony, and arsenic. Quite frequently, mines will use agitated leaching for high grade ore and heap leaching for marginal grade ores that otherwise would be considered waste rock. A common recovery plant is often employed for both operations.
Heap leaching has ancient origins, but its capabilities in extracting materials from low grade ore sources have only truly been realized in recent decades, with a constant evolution of the process ongoing.

Heap leaching is BAT for suitable ores because it allows the economical processing of ore that would otherwise be uneconomic under con ditions that can technically achieve regulatory acceptable levels of environmental risk mitigation.
The leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it percolates through the heap. The impregnated solution can then be collected at the bottom of the heap so that the copper can be recovered.
MINING spoke with some leading heap leach experts earlier this week at the first annual Heap Leach Solutions Conference in Vancouver. For the benefit of the layman, heap leaching is an

Heap leaching is done on ores of semilow gradethat is, high enough to be brought to the surface for treatment. This method is increasing in popularity as larger tonnages of semilowgrade ore are mined.
Cyanide Leaching Of Gold . Arsenic and antimony do present a larger problem, by reacting with the cyanide and using up all of the excess oxygen, leaving little or no oxygen to effect the dissolution of gold. And while the pile of ore is called a heap, it is not a haphazard pile of rocks. Much thought and design goes into the making of a
New techniques for tailings treatment and sulfide ore recovery will see lowcost environmentally friendly heap leaching take another giant leap forward.
Heap leaching is a process that extracts valuable metals from ores by dissolving the metals in a solvent. The valuable metals can then be recovered from the solution by a variety of methods. Heap Leaching is an ancient process; leaching metals out of ore goes back nearly 500 years.
In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process.
With its low construction investment, quick production result and good flexibility, gold heap leaching process has rapidly occupied a significant position in the ore dressing process. Gold heap leaching processes include
