hematite mines utah hematite is the most important ore of iron and it has been used by people as a pigment for at least 40,000 years. importance of hematite ore in the economy;
The Economic Importance of Hematite Although other minerals, such as magnetite, have higher iron concentrations, hematite is so much more abundant that it is easily the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist.

Hematite has a wide variety of other uses, but their economic significance is very small compared to the importance of iron ore. The mineral is used to produce pigments, preparations for heavy media separation, radiation shielding, ballast, and many other products. Hematite's Streak: All specimens of hematite will produce a reddish streak. The streak of a mineral is its color in powdered form
With few exceptions, the economic uses of hematite revolve about its iron-rich composition and characteristic red color. Its name comes from ‘haima’, the Greek words for blood, a reference to hematite’s distinctive color. Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In
Hematite (or haematite) Hematite is the most important ore mineral of iron. It is an oxide mineral and is found in a variety of colours, with red, orange and brown occurring when the iron in hematite begins to rust. There are also several forms of hematite, some of which are: kidney ore, a massive, botryoidal (lumpy) or reniform (kidney shaped) form; specularite, a micaceous (flaky) form
It is important at this stage to distinguish between an iron ore and an iron mineral. An ore is the quantity of a mineral resource that can be extracted and is economically viable and legal. An ore mineral however is the chemical compound that contains the desired metal. For example, taconite is an iron ore that is mined extensively in USA, which contains the minerals hematite and magnetite
The iron ore deposits of economic importance occur in close association with BIF in Jilling–Langalata mining areas. The genesis of these high-grade hematite ores remains controversial while such studies incor- porating genetic models on high-grade iron ores. Mineralogy and geochemistry of banded iron formation and iron ores 621 Figure 1(b). Geological map of Jilling–Langalata iron ore
High-grade hematite ore is referred to as direct shipping ore (DSO) because after it is mined, the ores go through a relatively simple crushing and screening process before being exported for use in steelmaking. Australia's hematite DSO from the Hamersley region in Western Australia averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but
Hematite is economically the most important iron ore, since it is more abundant than magnetite. Hematite typically occurs as one of two varieties; a massive red earthy form or a black specular variety that has a strong metallic luster. The latter variety may be mistaken for magnetite, but is not magnetic. When rubbed across a rough hard surface metallic hematite also leaves a distinctive red

Screening is an important step for dry beneficiation of iron ore. Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and

The copper ore is crushed and then ground to a fine powder in Ball Mills. The fine ore goes to banks of Flotation Cells in the Copper Concentrator, and the Copper Sulfide Minerals are collected on bubbles. The Concentrate is dried and the Sulfur is

Hematite, heavy and relatively hard oxide mineral, ferric oxide, that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for ‘blood,’ in allusion to its red color. Learn more about hematite in this article.
