<p>The present invention relates to a pretreatment method for recycling magnesium thermal reduction slag into resources. More specifically, the pretreatment method for recycling magnesium thermal reduction slag into resources comprises the steps of: sorting magnesium thermal reduction slag into a fine powder slag and a massive slag on the basis of a grain size by using a sieve; crushing the massive slag which has been sorted; and sorting the slag which has been crushed into a magnetic substance and a nonmagnetic substance on the basis of a magnetic force. The present invention sorts magnesium thermal reduction slag on the basis of a grain size and a magnetic force, thereby reducing differences in components and physical properties and differentiating the purposes of recycling. Accordingly, the present invention prevents the problem of deteriorating the quality of a recycled product and increases the usability of magnesium thermal reduction slag compared to an existing magnesium thermal reduction slag, thereby allowing the higher value-added recycling suitable for a purpose without unused magnesium thermal reduction slag.</p> |
