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
Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves. Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in

quartz and other gangue minerals (Yu et al., 2017). Therefore, low-grade hematite ores must be treated by mineral processing methods (e.g., flotation and magnetic separation) to obtain the iron concentrate. Prior to separation, the iron minerals must be liberated from the gangue minerals through comminution,
of a mineral. The natural or modified surface property of the mineral determines its ability to attach to an air bubble and float to the surface. Depending on the volume of samples (from a few kilograms to 1-2 tonnes) high or low capacity gravity equipment can be used. ALS Metallurgy has a fully integrated mineral processing laboratory.
