Types of iron ore: Hematite. Hematite gets its name from the Greek word for blood, haima, because of its reddish color. This is one of the types of iron ore that has very high iron content, and although the iron content of hematite itself is lower than that of magnetite, the mineral sometimes occurs in higher-grade deposits, often referred to as direct-shipping ore (DSO). This means that, due to its high iron content, …

Haematite and magnetite are the most important iron ores in India. About 59% haematite ore deposits are found in the Eastern Sector while about 92% magnetite ore deposits occur in Southern Sector, especially in Karnataka. Of these, haematite is considered to be superior because of its higher grade.
Ore - Wikipedia
Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.. The grade of ore refers to the concentration of the desired material it contains.
Iron ore pricing explained | Metal Bulletin.com
For these reasons, the rule of thumb is “higher Fe grade, higher price.” Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium. Most steel mills use a blend of different grades ...
