Heap Leaching Technology
Permeability
Insufficient heap permeability is one of the most common causes of failure of heap leaching projects.
Poor permeability means slow solution flow and results in uneconomic leach cycle times. In addition to this, recovery is reduced due to incomplete wetting of the heap.
Low permeability also limits air ingress, a necessity for bacterial leaching operations. If heaps are too permeable the solution-ore contact time will be insufficient also resulting in reduced or slow recovery.
One of the major contributors to low conductivity is fine particles and clays within the ore. Fines in the ore block the inter-particle pore spaces, reducing the overall void spaces and thus the permeability of the ore. In extreme cases heaps can ‘plug’ when fines are transported by the solution and packed into an impervious layer deeper in the heap.

Oxygen and the Aeration elements from your Leaching Pad
Oxygen and aeration is one of the most important elements in the leaching process. With ARS technology system we ensure to control the flow rate m2 and the efficient aeration of oxygen . The ratio of oxygen and the aeration during the leaching is the most important and critical aspect for the ore by controlling the percolation and the oxygen in to the leaching ore .
Over-adding the ILS solution and saturates the ore ,we drives out the oxygen and aeration during the leaching.
In order to achieve maximum leaching efficiency we required to control the flow leach solution movement through the ore by capillary action.
How You Can Achieve Good Uniformity Percolation
With our Drip LeachLine !
By optimal drop size, for the best uniform percolation and maximum metal extraction
Drip Leach Line The best Uniform Percolation.
To meet the unique challenges of the mining industry and to improve the productivity of leaching methods, A.R.S developed the Drip Leach Line, an innovative solution comprising a series of dripperlines equipped with highly turbulent labyrinth flat drippers, wide passages and short flow paths, Leach Line is always installed on top of the line. Its significant filtration area prevents large solid particles from entering and clogging the dripper. In addition to self-flushing, it ensures the dripper’s efficiency throughout the whole leaching cycle, leading to improved metal recovery.
A.R.S provides reliable services in engineering, hydraulic design and technical support. Implementing a hydraulically efficient and cost effective system, the company’s mining team assists the metallurgical engineer to achieve the appropriate and desired irrigation rate.
AR.S systems are complemented by a wide variety of products, each resistant to acid and alkaline solutions.
