8.2 Mining and Ore Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size and grade. Relatively large deposits that are quite close to surface and somewhat regular in shape are mined using open-pit mine methods (Figure 8.1.5 in Section 8.1 ). Creating a giant hole in the ground is generally ...
