MAGNETIC SEPARATION METHOD OF STEEL-MAKING SLAG, AND MAGNETIC SEPARATION DEVICE OF STEEL-MAKING SLAG
To provide a magnetic separation method of steel-making slag capable of heightening Fe concentration in recovery, in a magnetic separation method for recovering a ferrous compound and metallic iron by magnetic separation from slurry steel-making slag.SOLUTION: A magnetic separation method of steel-making slag includes steps of: bringing slurry containing crushed or pulverized particulate steel-making slag into contact with the surface of a rotary drum having a magnetic field formed on at least a part of the surface; and removing a liquid component contained in the slurry rotated and moved along the surface of the rotary drum, by spraying gas onto the surface of the rotary drum.SELECTED DRAWING: Figure 1
【課題】スラリー状の製鋼スラグから磁選により鉄系化合物および金属鉄を回収するための磁選方法において、回収物中のＦｅ濃度を高めることができる製鋼スラグの磁選方法を提供すること。【解決手段】本発明に係る製鋼スラグの磁選方法は、表面の少なくとも一部に磁場が形成された回転式ドラムの、前記表面に、破砕または粉砕された粒子状の製鋼スラグを含むスラリーを接触させる工程と、前記回転式ドラムの表面に気体を吹き付けて、前記回転式ドラムの表面に沿って回転移動する、前記スラリーに含まれる液体成分を除去する工程と、を含む。【選択図】図１
