Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
The results of this study demonstrated that lowgrade iron ore fines can be upgraded by means of STET triboelectrostatic belt separator. Based on STET experience, the product recovery and/or grade will significantly improve at pilot scale processing, as compared to the benchscale test device utilized during these iron ore trials.
Uses of Hematite (Iron Ore) Hematite is the world''s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces. 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.
