Environment protection expenditure by the mining industry Total expenditure for environment protection by the mining industry increased by 6% from in 199697 to in 200001. Metal ore mining accounted for most of this expenditure (58%), followed by coal mining (24%), and oil and gas extraction (8%).
It is primarily from waste in the mining of sulphide ores that serious environmental problems can arise due to their content of iron sulphides such as pyrite and pyrrhotite. When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind, it will crumble through an oxidation process.

Iron mining refers to the excavation of iron ore, most of which is used as a key component in the production of steel. Most of the iron ore in Wisconsin can either be classified as taconite (2535% iron) or highgrade ore (5070% iron). While Wisconsin is known as an agricultural state, it started as a mining state in the mid19th century.
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
