Iron Ore Mining Artifacts
Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel.
hematite ore classifier production line
About Hematite Hematite is a common oxide mineral in iron ore. The application of hematite often requires beneficiation processing. For the extraction of iron the hematite magnetic separation production line is generally used. The process technology is mature the operation is smooth the production efficiency is high and the failure rate is low.
Hematite: A primary ore of iron and a pigment mineral
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.

The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts.
