New approaches for extracting and recovering metals from mine tailings

Recently, extraction of metals from oxidised ores using reductive, rather than oxidative, bioleaching has been described (Johnson et al., 2013). In contrast to conventional biomining, this requires the addition of an extraneous material, such as elemental sulfur, to act as the electron donor for bacteria that reduce ferric iron minerals.

The metal-laden ferrous iron-containing PLS is then pumped to the surface for metal extraction and regeneration (Figure 2). This cycle would continue until the in situ ore body is mostly depleted of target metals.
