This study explores the role of industrial iron ore mining on land change and local livelihoods in the Tonkolili mineral rich region of northeastern Sierra Leone.
The environmental impacts of mining are the subject of increased community scrutiny. In response to crucial environmental and community concerns we have invested over two decades of R&D developing science and technologies that help minimise environmental impacts prior to, during and post-mining, to support a sustainable future for the industry …
This study asks: Do environmental impacts from historic iron mining in the Mesabi Range persist? Mapping historic mining and current lake water quality within the Mesabi Iron Range suggests that they do. HUC-12 subwatersheds that experienced historical mining activity are also the subwatersheds with a greater percentage of …
The iron ore mining and dressing industry accounts for a large share of the ferrous metal mining and dressing industry, and the iron ore resource tax represents 93% of resource tax revenue obtained from the ferrous metal mining and dressing industry.
The world iron ore mining industry's GHG emissions are almost exclusively linked to energy consumed during mining and removing of vegetation during the production process, providing an environmental challenge for the industry. ... environmental, and economic impacts of mining of local communities raise questions about the relationship …

In this study, the impacts of mining iron ore particularly resulting from open-cast mining are covered with special reference to environmental issues (such as Air, Water, Soil), and health hazards on the population of the mining region.
Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its extraction and production. The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of …
