Iron ore Wikipedia. Iron ores are rocks and minerals from which metallic iron can be economically extracted. . The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 37% silica and less than 3% aluminium. are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content.

Rock that is rich in a valuable mineral is referred to as ore. Most iron ore contains some form of iron oxide (e.g. Fe 2 O 3, Fe 3 O 4). 3 In order to extract iron from iron ore, one must first remove the unwanted minerals, then remove the oxygen from the iron. The latter step can only be achieved with a chemical reaction.

Jul 29, 2019Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.
