Environmental impact of iron ore mining

When iron ore mining exposes metal-bearing ores rather than exposing ore bodies naturally through erosion, and when mined ores are placed on earth surfaces in mineral dressing processes, the risk of contamination increases. [14] Public Safety [ edit] People are naturally drawn to old mining sites, but they can also be dangerous.

All of this means that productivity, as measured in tons produced per worker per shift, can be 5 to 50 times lower, depending on the mining technique, than on the surface. Balanced against this is the fact that underground only ore is mined, whereas in the open pit there are often several tons of waste stripped for each ton of ore.

Iron Ore Statistics and Information

Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries. The seven largest of these producing countries
