Dilution rate: In the process of ore mining, due to the mixing of waste rock and gangue, loss of highgrade ore, dissolution or loss of some useful components, etc., the grade of the mined ore is lower than the geological grade of the ore in the industrial reserves calculated before mining. This phenomenon is called ore dilution.

Crushing At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. 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.

Mining Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on ...
