What is Hematite? Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3.It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world.. Hematite is the most important ore of iron.Although it was once mined at thousands of locations around ...

Hematite separation process is suitable for complex structure hematite such as hematite and impurities with uneven distribution of particle size, ore with large content of fine particle, ore with small amount of magnetite and the gangue minerals containing quartz or kaolin.

Gravity separation and Ore Beneficiation. Gravity separation is the oldest known ore beneficiation technique and is practiced extensively in ‘Nature’. Earliest recorded human use of gravity separation was recovery of gold by panning from the Upper Nile by ancient Egyptians, dating back to 1900 BCE.

Processes for Beneficiation of Iron Ores Iron is an abundant element in the earth’s crust averaging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore grade.
