In addition, these precious and special metals have very low concentrations in ores mining, smelting, and refining these metals therefore have a particularly large environmental impact. Recovering these metals from defunct electronic equipment would result in a fraction of the effect on the environment [20].

Was aluminum produced from recycled aluminum, or was virgin aluminum used and produced via bauxite ore, alumina, smelting, etc. (If the source was not recycled aluminum, the environmental impacts of aluminum production must be identified.)... 

In many regions of the world where ores of toxic elements were exploited and smelted for long periods, the environmental impact of wastes is often an unresolved problem, mostly owing to the lack of adequate reclamation.

There is a stark contrast between the results for the aluminium smelting sector and those for the other sectors. In short, because aluminium smelting is assumed to be a global market, even relatively small changes in cost are predicted to have significant impacts on the competitiveness of UK/EU companies relative to global companies (which are assumed not to have environmental policies applied to them). 

In practice, there are various methods and approaches that one can use. However, in studies done to prevent environmental risk in areas and where the entire mining operation and smelting cycle are concentrated, a complex comprehensive analysis is most efficient and useful. Research into the human-caused impacts on mining territories represents a new step in the sphere of studying and analyzing mining s impact on the environment.
