A mixture separating method for separating, by type, a mixture containing at least two types of particles, particles of one type of which are made of a paramagnetic or diamagnetic substance, or for separating the particles of the one type from the mixture, comprises a step of applying a magnetic field whose magnetic field gradient has a vertical component and a horizontal component to a supporting liquid stored in a separating tank, a step of placing the mixture into the supporting liquid to which the magnetic field has been applied, and guiding the particles of the one type using the magnetic field such that the particles of the one type are positioned in the supporting liquid at a predetermined height from a bottom face of the separating tank while horizontally traveling, or a step of placing the mixture into the supporting liquid to which the magnetic field has been applied, and causing the particles of the one type to magnetically levitate at a liquid surface of the supporting liquid and horizontally travel using the magnetic field, a step of collecting the particles of the one type positioned at the predetermined height or at the liquid surface of the supporting liquid, wherein particles of another type of the at least two types of particles are positioned at a position vertically different from that of the particles of the one type, between the bottom face of the separating tank and the liquid surface of the supporting liquid. |
