Hematite is a kind of iron oxide ore, the main component is Fe2O3, it is dark red, the specific gravity is about 5.26, and it contains 70% Fe and 30% O.

Steel is an important industrial raw material and plays an important role in industrial construction. Studying the efficient utilization of complex refractory iron ore with large reserves is of great significance to ensure the strategic safety of China's iron and steel industry. Focusing on the typical mixed iron ore of siderite (FeCO3) and hematite …

Iron is the principal raw material for steel industries and Hematite is a principal ore of iron. Quantitative and qualitative estimation of iron in its ores is a crucial factor before its extraction. In this work, quantitative chemical analysis of iron was carried out from the collected seventy-two hematite samples from Pokhari, Nawalparasi. …

Now Hematite iron ore processing is as follows: Weak Magnetic - Strong Magnetic Separation Commonly, weak magnetic separation can be added before strong magnetic …

According to the different particle sizes of ore embedded, hematite can be divided into coarse-grained hematite, medium-grained hematite and fine-grained hematite. Coarse-grained hematiterefers to iron ore with an embedded particle size of 2mm or more. It is easy to extract iron from this kind of haematite by …
