Extraction of Iron from Haematite - KDRChemistry

Step 1: The Iron ore is crushed and broken into smaller pieces, with gravity separation process washed with water. Step 2: The raw materials are added into the top of the furnace : Iron ore Haematite, Fe2O3, Coke Carbon, C, Limestone CaCO3
Study on kinetics of thermal decomposition of low LOI

· The majority of low grade hematite iron ore resource at present is fragile in nature because of its association with good amount of goethite, kaolinite, and gibbsite. As per iron ore formation, goethite generates from hematite due to weathering. The goethite associated with hematite is called vitreous goethite which is hard and crystalline

Extraction of Iron from Haematite

Haematite magnetic separation method mostly adopts a weak-strong magnetic separation method, which is used for the extraction of iron from haematite-magnetite mixed ore. Tailings of low-intensity magnetic separation are sent to strong magnetic roughing and scavenging after thickening, and the strong magnetic roughing concentrate is concentrated and selected by the strong magnetic separator
