Issues surrounding the extraction of the metals from their ores are the use of energy and the production of carbon dioxide during the processing. In the blast furnace, there is a lot of CO 2 produced, since carbon is used as the reducing agent. During the production of aluminium, the carbon anodes burn away in the oxygen that is produced during the electrolysis of the bauxite, producing carbon dioxide.
However, the process of obtaining Uranium through mining and processing ore also poses serious risks to people and the environment. To complicate these issues further, historically in the United States and around the globe the negative impacts of Uranium mining have fallen disproportionately on low income and minority communities.

15/10/2014· The energy costs required to refine metal values contained in ore to concentrates constitute the majority of the cost to produce metals. On average across the mining industry, 44% of the total electricity consumption is dedicated to crushing and milling activities ().Size reduction operations, nearly 150 × 10 9 kW h, are the largest single consumer of energy during mineral processing activities.
The process, called gold cyanidation, makes gold water-soluble, and thus easier to isolate from the ore.
01/01/2007· The impact of declining ore grade on GER as shown in Fig. 11 comes about largely because of the additional energy that must be consumed in the mining and mineral processing stages to move and treat the additional gangue material. Once a concentrate or mineral product of a specified grade has been produced, emissions from downstream processing (e.g. smelting and refining) are
The results showed that loading and hauling make the largest contributions to the total greenhouse gas emissions for the mining and processing of iron ore and bauxite.
Smelting is the process of heating ores to release the metals in them. This process separates the impurities from the metal, but also creates air pollution because gases that are created as by
Environmental impact of Iron ore mining on quality of surface water and Health of the inhabitants of I takpe, Nigeria was investigated. Since the commencement of iron ore mining in Itakpe in 1979
