Agglomeration technique improves heap leaching …
When carried out properly, agglomeration through the use of an agglomeration drum can offer a greatly improved leaching process through improved heap permeability, an early start to the leaching process, increased particle penetration and greater particle strength. Ultimately, this aids in the effort to recover as much ore as possible in a time when resources — particularly copper — are ...

Agglomeration Drums in the Heap Leaching Process
Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time.. While this process has proven to be efficient, often chosen for its cost-effectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.

Heap Leaching Systems. FEECO can supply a complete package consisting of a rotary ore agglomerator, and the necessary material handling equipment to feed the agglomerator, as well as carry material to the heap leach pads.. FEECO is a preferred partner for the heap leaching process because of our vast experience in the agglomeration field for over 65 years.

Heap leaching is a method used to recover precious metals such as gold and copper from low grade ores. In copper heap leaching, the ore is stacked in approximately 6.1 m (20 ft) ‘lifts’ and an acidic leach solution (raffinate) is sprayed on the top of the heap. As the raffinate percolates through the heap, the copper is solubilized and retained in the liquid phase. The flowing liquid can ...
Heap Leaching Agglomeration
Agglomeration heap leaching increased silver recovery to 90 pct of the leachable silver and decreased the leaching time to 7 days. Gold Heap Leaching 2500 TPD An operation in northern Nevada (fig. 7), which has produced gold by agitation cyanidation and countercurrent decantation for several years, discovered a new ore deposit several miles from the working mine.
Crushed ore agglomeration and its control for …
The drum agglomeration is considered as a pretreatment step for the heap leaching of copper and gold ores whereas the agglomeration of uranium and nickel ores has received less attention over the past years. The acceptance of binder application for acidic leaching systems is limited primarily due to the lack of acid-tolerant binders. The use of binder depends mainly upon the cost ...
REVIEW OF AGGLOMERATION PRACTICE AND …
ABSTRACT This article reviews agglomeration practices for precious metal and copper heap leaching. Both industries prefer drum to conveyor agglomeration, particularly for clayey ore or ore having a high fines content. Precious metal heap leaching operations opt for cement in a dosage from 2.5 to 10 kg cement/t of ore (5–20 lb/ton) added to a cyanide solution.
Heap leaching - Wikipedia
The mined ore is usually crushed into small chunks and heaped on an impermeable stone or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process…

01.02.2009 · Agglomeration techniques are widely used by industry to form fine particles into larger masses that are easier to handle and process. One area where agglomeration is potentially useful is in heap leaching operations. Without agglomeration, fine particles travel through the heap, clogging the spaces between the larger particles and resulting in poor leach solution flow.

While heap leaching for copper was under discussion in the 1920s, he said, leaching of residual material in old stopes began in 1923 at Bisbee, Arizona, USA. This was followed by the in-situ leaching of ore left over from block caving at several mines, including Ray and Miami; in the late 1950s, Miami created a block-cave stope specifically for ...
