Circuit modelling and simulations are often carried out using a floatability component approach (e.g., Alexander et al., 2000). In this approach, the flotation characteristics of the each of the minerals phases in the feed are determined, using either laboratory batch or plant flotation data.

To maximise the value of a mining operation and minimise its environ- mental and social impacts, all processes—from the ore deposit to the final product and waste streams—should be optimised together. However, mining and metallurgical processes are inherently variable and uncertain due to the natural heterogeneity of ore deposits and the limited information and incomplete models …

The most sustainable mine is the one that should not have been mined because of lack of sufficient resources. Mining exploration and appraisal heavily relies in geological, geophysical and geochemical analysis, but is subject to considerable uncertainty. In that context, mineral prospectivity mapping (MPM) is particularly important for exploring undiscovered mineral …

A mining complex is a type of value chain whereby raw materials (minerals) extracted from various mineral deposits are transformed into a set of sellable products, using the available processing streams. The supply of materials extracted from a group of mines represents a major source of uncertainty in mining operations and mineral value chains.
