A. Jankovic, in Iron Ore, 2015. 8.1 Introduction. Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements.
Jan 04, 2016· One of the major advantages hematite ore has over other types like magnetite ore is its high iron content. That makes the iron extraction process much less costly and time consuming. In addition, hematite ore only goes through one stage of screening and crushing, while magnetite ore has an additional round of processing. Types of iron ore ...
The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Almost all iron ore is used in blast furnaces to make pig iron, which is the main material for steelmaking. Small amounts of iron ore are used in other applications such as coal wash plants and cement manufacturing.
May 03, 2017· Mining and processing hematite and magnetite ores. High-grade hematite ore is referred to as direct shipping ore (DSO) because, once mined, the ore goes through a relatively simple crushing and screening process before being exported for use in steel making. Australia's hematite DSO from the Hamersley province averages from 56% to 62% iron.

Jan 31, 2018· Difference Between Magnetite and Hematite Definition. Magnetite: Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Hematite: Hematite is an iron ore where iron can be found in the form of Fe 2 O 3. Presence of Iron. Magnetite: In magnetite, iron is present in the form of Fe 2+ and Fe 3+.
Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without ...
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

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, the most desirable iron ore because of its high iron content, is found throughout the world, with its highest abundance being seen in Australia, Brazil, and parts of Asia. Since the 1960's, high-grade hematite ore has served as the major source of iron mined in Australia. It comprises 96% of the iron ore exports from that continent.
