In the case of dynamic heap leach, after the leaching process, spent ore is transported by conveyor belts to be disposed into dumps. It is common to observe physical stability problems in these dumps, that could compromise the operation of the stacker equipment along with the operational continuity of the mine.
Operational controls of the spent ore after the leach pad process, are needed to obtain the particle size distribution. Carry out periodic maintenance of the drainage system in the heap leach pad, to ensure its correct functioning. Permanent control of water content of the spent ore in the dump. Build a temporary dump for the material with ...
Heap leach periods vary depending on the type of ore, and leaching method ranging from a few days to months and even a couple of years. Subprocesses in heap bioleaching have …
Hycroft is in the process of expanding its mining operations to incorporate its proprietary sulfide oxidation and heap leach process. This will require the construction of a new leach pad capable of supporting the 34-year resource life at Hycroft. Construction began on the first stage of the leach pad in late 2019.

The BASF Intelligent Mine Heap Leach Optimization Application: Stabilizes the process by reducing p80 size reduction variability, optimizing particle size distribution with minimum fines generation and optimizing acid to fines ratio in the agglomeration unit operation.; Increases heap deposition throughput maximizing reclaim …
Open heap leaching is primarily done in drier climates, but pads built in wet climates are more likely to need covers and runoff management systems. Collecting and Concentrating the Leachate Once the water and lixiviants trickle through the multiple layers of mounded ore fines, it finally reaches the liner layer at the bottom.
Layfield Environmental Containment can provide several types of heap leach geomembranes. We recommend Enviro Liner® 4000 and Enviro Liner® 6000HD in 40 and 60 mil thicknesses for heap leaching applications. These geomembranes are highly flexible and are well suited for placement under pads of blasted rock. Both Enviro Liner® 4000 …
