Thulium and lutetium are the two least abundant rare earth elements but they each have an average crustal abundance that is nearly 200 times greater than the crustal abundance of gold 1. However, these metals are very difficult to mine because it is unusual to find them in concentrations high enough for economical extraction.

The ore is a free milling conglomerate with negligible sulphide content. Weathering has affected rocks near the surface and a higher degree of weathering is associated with increased porosity and increased Heap Leach dissolution and recovery. The North Heap Leach was commissioned in 1998 to process the initial high porus ore.

Sep 19, 2021· Mined ore quality varies due to natural differences in mineral concentrations, irregular ore boundaries, and mining processes. Grade control systems attempt to segregate ore and waste so ore is sent to the process plant and waste is discarded. Variation is almost always present within the material sent to the process plant (Figure 1).
