The cobalt processing route is determined on the deposit and ore type, and particularly the dominant cobalt-bearing mineral species. After crushing and grinding, sulphide ores which contain cobalt-bearing minerals are typically processed using a combined froth flotation – pyrometallurgical route while for oxide ores a …

The significant consumption of limestone has led to the depletion of certain mineral resources (Jiang et al., 2019). Therefore, replacing limestone with calcium-rich solid waste as a flux for iron ore sintering is a promising approach to achieve large-scale environmentally benign disposal without generating new waste.

Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this way it is possible to focus the mining on the orebody itself. In some cases, the near-surface part of an orebody is ...
