Primitive people discovered that hematite could be crushed and mixed with a liquid for use as a paint or cosmetic. Even though hematite has a highly variable appearance, it always produces a reddish streak. It can crystallize during the differentiation of a magma or precipitate from hydrothermal fluids moving through a rock mass. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an … Tiger Iron is a sedimentary deposit of approximately 2.2 billion years old that consists of alternating layers of silver gray hematite and red jasper, chert or even tiger eye quartz. Hematite is the principle ore of iron. It has the same crystal structure as corundum (Al 2O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C (1,740 °F). In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist.

An abundance of hematite in Martian rocks and surface materials gives the landscape a reddish brown color and is why the planet appears red in the night sky. A. Jankovic, in Iron Ore, 2015. and shale. Save Compare 0. The streak on the right still has a trail of glittery fragments that must be gently removed for proper evaluation. 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. Hematite is found as a primary mineral and as an alteration product in igneous, metamorphic, and sedimentary rocks. This allowed the formation of iron deposits hundreds to several thousand feet thick that are laterally persistent over hundreds to thousands of square miles. Hematite is widely spread in rocks and soil. What is Iron Ore? In the photo above, the streak on the left has been cleaned of fragments, and you can see that it is a reddish brown.

It has been mined at many locations around the world and has been traded extensively as a red pigment. Van Hise and Leith (1911) describes the ore as containing soft red hematite (paint ore) mingled with harder red slatey hematite and steel blue hematite nodules. Instead, if the specimen is magnetic and has a reddish streak, it is most likely a combination of hematite and magnetite. The ore has high iron content, typically between 56% and 64% Fe. The best way to learn about minerals is to study with a collection of small specimens that you can handle, examine, and observe their properties. This is because mining of this ore started quite early when other ores of iron were not known. Then a group of cyanobacteria became capable of photosynthesis. Most ore is now produced in China, Australia, Brazil, India, Russia, Ukraine, South Africa, Canada, Venezuela, and the United States. Magnetite is an iron oxide mineral that is generally black and highly magnetic. This is the iron oxide, which contains Fe (3+) ion. China, Australia, Brazil, India, Russia, Ukraine, South Africa, and the United States are the world’s leading producers of iron ore (includes hematite, magnetite, and other ores).
