Heap Leaching is a low-cost method for extracting valuable metals from crushed or ground mineral ores. This cost-effective and flexible approach has revolutionised the mining industry, particularly for metals like copper, gold, silver and uranium. However, the efficiency and productivity of Heap Leaching operations can be significantly enhanced by integrating mobile equipment. These mobile solutions offer a range of benefits, from increased flexibility to reduced operational costs, making them indispensable in modern mining operations.
The key benefits of utilising mobile equipment in Heap Leaching applications are:
1. Enhanced Flexibility
One of the primary advantages of mobile equipment in Heap Leaching applications is its unparalleled flexibility. Traditionally, fixed conveyor systems limit the ability to adjust to changing mining conditions or to move locations quickly. In contrast, mobile conveyors and stackers can be easily relocated and reconfigured as the Heap Leaching pad grows. This mobility ensures that the system can adapt to variations in ore deposit locations and changes in production requirements, allowing mining operations to maximise ore recovery while minimising downtime.
2. Cost Efficiency
Mobile equipment can significantly reduce both capital and operational expenses. With fixed or semi-mobile systems, any change made in the Heap Leaching operation, such as expanding the pad or moving to a new location, requires substantial investment in new conveyors and support structures. However, mobile equipment can be redeployed across multiple sites with minimal setup time, reducing the need for costly new installations. Additionally, mobile systems typically require less downtime for preventative maintenance than fixed systems, leading to further cost savings over the project’s life.
3. Improved Material Handling
In Heap Leaching, efficient material handling is crucial to ensuring that the leaching solution is evenly distributed over the ore, maximising precious metal recovery. Mobile stacking systems are designed to optimise material placement, ensuring a consistent and uniform heap, which is vital for effective leaching. Unlike stockpiling with trucks and dozers, the material is not compacted, and this soft stockpile allows the acid to permeate through the ore, giving better leaching rates. These systems can also handle various materials, from finely crushed ores to coarser aggregates, ensuring versatility in different mining environments.
4. Increased Operational Safety
Safety is a top priority in mining operations, and mobile equipment contributes significantly to a safer work environment. By reducing the need for extensive infrastructure and manual material handling, mobile systems minimise the risk of accidents. Dozers, wheeled loaders, and trucks are not needed to work at heights, which reduces the potential for accidents. Moreover, many modern mobile systems come equipped with advanced safety features such as remote operation and automated controls, further reducing the risk to on-site personnel and operators.
5. Types of mobile systems
Telestack can supply a variety of systems:
• fed by tripper conveyor via link conveyors, cross conveyors and Horizontal Index Conveyors to the stacker
• Fed directly by ADT trucks to truck unloaders, link conveyors, cross conveyors and Horizontal Index Conveyors to the stacker

6. Customisation
Telestack can supply units designed with componentry to handle impregnated ore with various acids, including optional extras for upgraded paint, acid-resistant belts, acid-resistant scrapers and liners, stainless steel control panels and instrumentation.
Telestack can supply units designed with winterised componentry to handle operating temperatures of down to minus 40, including winterised belts, low-temperature scrapers, insulated and heated control panels, low-temperature oil, low-temperature bearings, insulated hydraulic tanks and low-temperature seals on hydraulic oil.
7. Environmental Benefits
Mobile equipment can also offer environmental advantages in Heap Leaching operations. Since these systems are designed for minimal site disruption, they reduce the environmental footprint of mining activities. Using mobile equipment reduces the need for wheeled loaders, dozers, trucks, and diesel consumption, reduces dust generation, and lowers emissions compared to traditional fixed systems. Furthermore, their efficiency in material handling helps ensure that the leaching process is as effective as possible, minimising waste and reducing the overall environmental impact.
