The chapter presents a study on wastewater from the iron and steel industry and mining. Wastewater from iron and steel works, where the smelting of pig iron in blast furnaces and of steel in open hearth furnaces takes place, contains a considerable amount of oil, dust, acid, iron, and other metals.
mercury cycling in NE Minnesota where an economically important ironmining district ("taconite") operates within a region prized for its many fishing lakes. As is the case in most regions, mercury loading in NE Minnesota is dominated by atmospheric deposition. Most mercury deposited on land is revolatilized, but a

Context: Iron is an essential element for most life on Earth, including human beings and its accurate determination is extremely important. A simple and sensitive spectrophotometric method has been used for the determination of iron concentration in blood serum and compare with atomic absorption spectrophotometric method.
A mineral deposit is a natural concentration of minerals in the earth's crust. The degree of concentration is called the "grade" of a mineral deposit. An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine.
The iron(II) oxidation rate equation is a function of the iron(II), hydroxide, oxygen and suspended solids concentrations. The optimum suspended solids concentration for iron(II) oxidation in a fluidizedbed reactor is 190 g/ℓ. Upflow velocity has no influence on the rate of iron(II) oxidation in the range 5 .

The decline of copper and ironore mining was a serious economic setback for the Upper Peninsula, but with the development of new mining and processing methods, this mining industry has recovered somewhat. The employment high in ironore mining was 6,972 in 1952. Bog iron
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
