Apr 25, 2017 Environmental Impacts Of Mining . As mentioned previously, mining activities can harm the environment in several ways. These are as follows Air Pollution . Air quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining.Effects Of Mining on the Environment and Human Health Impacts of strip mining Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land.
Environmental impact of steel production Mining of iron ore. The main ingredient in the production of steel is iron ore mined from Earth. Over 2,000 million tons of iron ore is mined mined a year - about 95 percent is used by the steel industry.
8 The environmental impact of steel production. Steel production has a number of impacts on the environment, including air emissions (CO, SOx, NOx, PM2), wastewater contaminants, hazardous wastes, and solid wastes. The major environmental impacts from integrated steel mills are from coking and iron-making.
Aug 26, 2008 Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.

Abstract. Mining plays a vital role in the economic development of many countries. The emerging economies are now major players in the production and availability of key commodities such as copper (70 ), bauxite (40 ), iron ore and precious metals. Mining also has a positive impact on the economy of many countries.
The primary investor in the country’s ore mines, African Minerals, was a new player in the industry, with no proven track record globally—a risky choice in a place like Sierra Leone, which is known to be a complicated environment.
