The processing plant at SGM is a conventional gravity/leaching process which recovers gold from both underground (sulphide) and surface (oxide) ore sources. Processing involves a two-stage crushing, milling and a Carbon in Leach (CIL) circuit. Most ore types require further liberation of the gold from sulphide materials.

What was the Paleogene latitude of the Lhasa terrane A

1 Introduction. Establishing the paleolatitude histories of terranes within N-S closing oceanic basins is a common approach to date collisional events [e.g., Gilder and Courtillot, 1997], such as the one between Greater India and the Lhasa terrane that bordered the Cretaceous Neotethyan ocean.Paleomagnetic investigations of the paleolatitude of the Lhasa terrane, which formed the southern edge ...

different leaching kinetics. When gold is directly exposed to the surrounding phase it has a fast leaching kinetic. On the other hand, gold attacked through ore porosity, like in heap leaching, exhibits slow dissolution kinetics. Figure 1 shows four different classes of gold, each one having a different leaching behaviour. One can see that gold ...
