The iron ore processing industry produces usable concentrations of ironbearing material by removing nonferrous rock (gangue) from lowgrade ore. In the United States, predominant iron ore is taconite which is a hard, banded, lowgrade ore. Ninetynine percent of the crude iron ore produced in the United States is taconite.

1. Introduction. For iron ore sintering technology, the granulation of iron ore particles is a highly important stage prior to the hot processing unit [1, 2].By means of granulation, the raw iron ore particles are agglomerated into the products with an appropriate size distribution, which guarantees the desirable green bed permeability and air flow rate for sintering [3].

Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Water scarcity dictates to limit the use of water in ore processing plants particularly in arid regions. Since wet grinding is the most common method for particle size reduction and mineral liberation, there is a lack of understanding about the effects of dry grinding on downstream separation processes such as flotation.
