Winning Consortium Simandou ("WCS") plans on commencing an iron ore mine in the Kankan Region, Kérouané Prefecture of Guinea, Africa. The Simandou area (Figure 1) is split into four mineable blocks, Block #1, #2, #3 and #4, of which Block #1 and Block#2 (Figure 2) are owned by WCS and is where the Simandou Project is located.
The significant increase in metal mining and the inevitability of the continuation of this trend suggests that environmental pressures, as well as related impacts, have become an issue of global relevance. Yet the scale of the impact remains, to a large extent, unknown. This paper examines the mining sector's demands on CO2 …

Rio Tinto's destruction of Juukan Gorge in Western Australia is another example of mining's impact on the environment and cultural heritage. In May 2020, Rio Tinto blew up a 46,000-year-old Aboriginal heritage site to expand their iron ore mine. This event sparked international outrage and highlighted the need for stronger regulations to ...
Abstract Open-cast iron ore mining is vital for the global economy, providing the raw material for steel production. It is cost-eective and allows for the ecient extraction of large ore quantities within shorter timeframes compared to underground min-ing. However, open-cast mining can have signicant environmental impacts. Open-cast iron ore mining
