Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

In this study, low grade hematite ores from Eğmir-Balıkesir, TURKEY were upgraded to obtain a hematite concentrate to be used in iron and steel industry.
The aim of this project is to propose methods for utilization of low grade iron ore especially Banded hematite Jasper (BHJ) and slimes. This is met by the following specific objectives:
important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the world, various beneficiation methods have been employed successfully in the laboratory as collectors for hematite and
In order to develop and utilise cheap iron ores with low quality for cost reduction, a hematite ore from Xinjiang province was investigated to determine the iron increase and silicon reduction ...
The principle ores of iron are hematite, (70% iron) and magnetite, (72% iron). Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite. Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite.
Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with "Sub-A" Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.
