اقرأ أكثرWhat is the magnetite hematite (siderite) separation process?
Why is hematite used over magnetite? Magnetite has more iron content. Hematite ore is simply mined, crushed, and after that screened into either lump or fines. It is then immediately sold as such. The ore has high iron content, typically between 56% and 64% Fe. Magnetite has higher iron content than hematite.
