Document Type and Number:
WIPO Patent Application WO/2019/054087
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a steelmaking slag magnetic separation method for collecting ferrous compounds and metallic iron by magnetic separation from slurried steelmaking slag, wherein it is possible to increase the Fe concentration in the collected product. This steelmaking slag magnetic separation method comprises: a step for bringing a slurry containing crushed or pulverized particulate steelmaking slag into contact with the surface of a rotating drum having a magnetic field formed on at least a portion of said surface; and a step for removing the liquid components contained in the slurry moving rotationally along the surface of the rotating drum by spraying a gas on the surface of the rotating drum.
