What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its abundance. …

22.1 Introduction. The iron ore production was about 2611 million metric tons in the world in the year 2010 [1]. Assume that (1) the iron ore production is kept 2611 million tons every year, (2) the price of final iron ore product is 75 US$ per ton, and (3) the ore recovery in the mining process is 85%. Under these conditions, the total ore ...

The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.

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.
