Leaching pads
WebIf fine particle material reports to the leach heaps, it negatively impacts leaching efficiency and other downstream processes, reducing metal production and increasing OPEX. The rate of reclaiming gravel from leaching pads is often limited by high residual moisture in these heaps - limiting the overall production rate. WebDump leach pads, which can hold raw and uncrushed materials for leaching. These pads need thick liners but can be built on sloped terrain and handle heavier loads than conventional designs. Valley fill pads, designed to take advantage of natural or excavated low points to hold a large volume without risk of slipping or spilling.
