The rock is mixed with water and ground in rotating mills until it is as fine as powder. separation the iron ore is separated from the taconite using magnetism. the remaining rock is waste material and is dumped into tailings basins. the taconite powder with the iron in it is called concentrate. pellets

Jun 16, 2011nbsp018332the presence of iron in ground water is a direct result of its natural existence in underground rock formations and precipitation water that infiltrates through these formations. as the water moves through the rocks some of the iron dissolves and accumulates in aquifers which serve as a source for ground water.

Pelletizing is a process made with finely ground concentrate. 5. ironore mining, treatment and transport. iron ore passes through a treatment stage to increase its iron content and to decrease the content of impurities, according to necessity. the processing grade depends on deposit types and economic considerations.

Iron ore fine. iron ore fines refer to a small particle of high grade direct ship ore. fines are high quality ground iron ore sands that must be sintered at first to create larger pieces before they can be used in blast furnaces. the grade is between 56 to 66 iron fe with the disadvantageous elements controlled through ore mixing.

Pelletizing is a process that involves mixing very finely ground particles of ore of less than 200 mesh with fluxing materials such as limestone and dolomite and then shaping them into balls 1015mm in diameter by a pelletizer, and hardening the balls by firing with heavy oil andor coal as a fuel.

Iron ore in a finely ground state is not easily transported or readily processed .thus it is necessary to agglomerate the fine ground ore into pellet using binders. inorganic binders introduce silica which decreases the final ore content of the pellet. hence organic binders were developed.
