The heap leaching approach to ore beneficiation is a growing trend in the mining industry, with applicability to various metals outside of copper and gold. Agglomeration is a valuable tool in maximizing recovery during the heap leaching process.
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

An important part of any heap leach circuit is the agglomeration drum, also called heap leach drum or Agglomerator. Materials like copper ore and gold ore benefit from the use of agglomeration prior to stacking and leaching the ore to extract the mineral.
Agglomeration Drums for Processing Gold Ore - feeco. One such advancement, is the use of agglomeration drums in the heap leaching process. The process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile, separating the gold from the ore. ...
Highlights Crushed ore agglomeration as a pretreatment step for heap leaching is reviewed. The acceptance of binder is limited due to the lack of acid-tolerant binders. Concise overviews of quality control and characterization tools are provided. Different agglomeration-heap leaching systems are summarized. HPGR grinding-agglomeration may have some advantages.
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 process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile, separating the gold from the ore. While this method has been used for decades with success, it has been greatly improved by the addition of an agglomeration drum to the process before the heap.

Jul 05, 2018· In the case of heap leaching, agglomeration relies on a binder (typically cement) and tumbling motion to cause coalescence, or the building of fines into larger particles. Agglomeration drums (sometimes referred to as ore drums or agglomerators) are the equipment of choice for agglomerating ore fines in preparation of heap leaching.

The coal gold agglomeration (CGA) process is a novel gold recovering technique, which has following advantages. Studies on gold recovery from amalgamation tailings by CGA process shows that about 88% gold can be captured by coal-oil agglomeration and the gross gold recovery is more than 85%. ADVANTAGES OF USING CGA
Adding an agglomeration drum to the heap leaching process also creates a more efficient leach because the leaching solution can be applied during agglomeration, creating a more homogeneous mix, and pre-starting the leaching process. ... Gold Ore Rotary Drum Agglomerator.
Sepro Tyre Drive Agglomeration Drums are available in several standard sizes to suit process specifications. They are the ideal solution for gold ores in which cement is the binding agent, as well for copper, uranium and nickel laterite ores, which require organic polymers to bind the fines.
