AGGLOMERATION-HEAP LEACHING OPERATIONS IN THE PRECIOUS METALS INDUSTRY By G. E. McClelland,' D. L. Pool,' and J.A. Eisele3 ABSTRACT During the 19701s, the Bureau of Mines investigated a particle ag-

Crushed ore agglomeration and its control for heap leach ...

01-02-2013· 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.

Acid curing and agglomeration for heap leaching | Request PDF

Heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal. Gangue, and its interaction with acid, ...

Binders for heap leaching agglomeration | SpringerLink

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. Poor flow of leach ...

Review of agglomeration practice and fundamentals in heap ...
