Underground mining has historically occurred in surface and near-surface (shallow) mineral deposits. While no universal definition of deep underground mining exists, humanity's need for non-renewable natural resources has inevitably pushed the boundaries of possibility in terms of environmental and technological constraints. Recently, deep …

Mineral processing involves the liberation and concentration of economical metals and minerals from mineral resources for metal extraction (Lottermoser, 2010). The economic purpose of mineral processing is two-fold: firstly, it reduces the bulk of the ore that needs to be transported and processed for metal extraction by using relatively cheap ...
