Oxidized PGM ores which typically exist near the surface, i.e., 15–30 m deep, are altered and oxidized as a result of exposure to atmospheric conditions and acidic ground waters. The major process occurring during oxidation of PGM ores is the decomposition of base metal sulfides and formation of iron oxyhydroxides. Numerous accounts exist

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 cheaper than making an underground …
