Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan. To uncover taconite reserves, the mine area is first "stripped ...

scaling mine waters (high in SO4 and Ca as opposed to high in Na and Cl). The major advantage of all treatment processes is that they can produce high quality water that can be used (sold) as drinking water. A major disadvantage of this class of treatment processes is the production of brine that requires disposal (and additional costs).

Iron usually occurs in soils in tertiary form, but in water saturated soils it is converted to binary iron, thereby enabling plant iron uptake. Plants may take up water insoluble iron compounds by releasing H + ions, causing it to dissolve. Micro organisms release iron siderochrome, which can be directly taken up by plants.

Water Recovery. Increased water recovery is important to many countries throughout the world due to the scarcity of fresh water. The more water that can be recovered from a tailing stream and, in turn, used again upstream in the plant reduces the amount of fresh water a mine needs. The cost of water is frequently one of the primary drivers for ...

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.
