Modern heap leaching practices include expanding technology that demands higher performance to meet strict industry requirements. In many cases, heap leach depths have increased to more than 500 ft of ore depth from only 50 to 65 ft a decade ago. This is a function of economic efficiency and surface area availability – both driven by closure and reclamation costs and minimization of impact on agricultural land by mining.
Wobbler® technology in heap leaching applications has a 90% uniformity by utlizing the same low pressures associated with drip systems. The mini-Wobblers® can be installed directly into dripper lines to complete the leach cycle or provide a final rinse.
