METHOD FOR DETERMINING OPERATION CONDITION OF MAGNETIC SORTING, AND METHOD FOR CALCULATING CLASSIFICATION PROPERTY OF MAGNETIC SORTING APPARATUS

To provide a method for determining an operation condition of magnetic sorting, in which ferromagnetic powder and/or paramagnetic powder is added and mixed into a particulate matter, and the mixture is classified by using a magnetic sorting apparatus, and which promptly obtains an operation condition suited for a classification point being the target.SOLUTION: Provided is a method for determining an operation condition of magnetic sorting, in which ferromagnetic powder and/or paramagnetic powder is added and mixed into a particulate matter, and the particulate matter is classified by using a magnetic sorting apparatus. The method includes a step in which an addition amount of the ferromagnetic powder and/or the paramagnetic powder is obtained by using: a concentration of a specific component in the particulate matter; a set classification point; and a relationship among the concentration of the specific component in the particulate matter acquired in advance, the addition amount of the ferromagnetic powder and/or the paramagnetic powder, and the classification point.SELECTED DRAWING: Figure 1 【課題】粉粒体に強磁性粉末及び／又は常磁性粉末を添加混合し、これを磁力選別装置で分級する方法において、目標とする分級点に適した運転条件を迅速に求めることができる磁力選別の運転条件決定方法を提供する。【解決手段】本発明に係る磁力選別の運転条件決定方法は、粉粒体に強磁性粉末及び／又は常磁性粉末を添加混合し、これを磁力選別装置を用いて分級する際の運転条件決定方法であって、粉粒体中の特定成分の濃度と、設定した分級点と、予め取得した粉粒体中の特定成分の濃度と強磁性粉末及び／又は常磁性粉末の添加量と分級点との関係と、を用いて強磁性粉末及び／又は常磁性粉末の添加量を求めるステップを含む。【選択図】図１
