iron ore mining which is better hematite magnetite
Hematite is economically the most important iron ore, since it is more abundant than magnetite. Hematite typically occurs as one of two varieties; a massive red earthy form or a black specular variety that has a strong metallic luster. The latter variety may be mistaken for magnetite, but is not magnetic.
