disposal of slagdisposal slag iron

US4666591A Slag disposal method Google PatentsA slag disposal method for disposing of slags produced in furnaces during iron or steel making processes comprises employing the steps of magnetic sorting of masses of crude slags of a size greater than a value ranging between 300 to 500 mm obtained from the furnaces into slags rich in iron (above about 50 to 60 percent) and slags not rich in iron (below about 50 to 60 percent) and then Keiji Imai, Shigenori Nagaoka, Shinji Kogumazaka, Takeshi Im
