Hematite: Fe 2 O 3: Granular massive or earthy: Brownish-red black: 2 5: Dark red or reddish-brown: 2 5-5: Often earthy dull appearance sometimes metallic luster Huge concentrations occur as sedimentary iron ore the most important source of iron: Limonite: 2Fe 2 O 3 3H 2 O: Earthy fracture: Brown or yellow: 1 5-4: Brownish-yellow: 3 6
Oxide minerals can also vary greatly in color form and appearance Some (for instance Hematite) have almost a metallic luster while others (such as Chrysoberyl) form as gemstones Due to the environment of their formation it is quite common for several species of oxide minerals to be found in close association
Classes of Minerals Minerals are classified according to their chemical properties Except for the native element class the chemical basis for classifying minerals is the anion the negatively charged ion that usually shows up at the end of the chemical formula of the mineral
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: A primary ore of iron and a pigment mineral 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
Chapter 12 THE ECONOMIC IMPORTANCE OF THE RARE EARTH ELEMENTS C R N E A R Y and D E HIGHLEY 12 1 Introduction The REE are relatively recent additions to the inventory of useful raw materials and since their first commercial exploitation in the latter part of the 19th century there has been a dramatic change in their industrial uses and the types of deposit worked
Iron ore is the main ingredient in steel which makes up 95 percent of the metals used in the world per year Two billion metric tons of raw iron ore are produced in a year The world's largest single producer of iron ore is Brazilian mining company Vale which produces over 350 million tons of iron ore annually
There are many other iron bearing minerals that are mined in small quantities but are not of huge economic importance due to low abundances or issues with the mining process For example pyrite (FeS) is extremely common but is not mined in large quantities because it releases toxic sulphur gases during processing and also retains sulphur impurities after processing
Hematite is the most important ore of iron although it was once mined at thousands of locations around the world today almost all of the production comes from a few dozen large deposits where significant equipment investments allow companies to efficientl What is the economical importance of iron ore
