Four Kinds of Hematite Ore Dressing Processes - Xinhai

The single weakly magnetic iron ore consists of hematite, siderite, limonite, and hematite in sedimentary and metamorphic, sedimentary, hydrothermal, and weathered deposits. Different kinds of iron ores Due to the variety of minerals and grain sizes, there are also many single weakly magnetic iron ore dressing methods.

Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C ...
