Heap Leaching: Extending Applications | E & MJ

Air flows through the heap are also critical to successful leaching, and if the level of water saturation in the heap is too high, it will effectively block the air flow, and hence the supply of oxygen to the leaching process. Measuring Success: By its very nature, heap leaching should be simple.
