The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes.

Under conditions of flotation separation of 2 × 10 −4 mol/L NaOL and pH 9.0, the zeta potential of magnetite particles increased from about −20 mV to about −25 mV. This indicates electrical double-layer repulsions between an air bubble and negatively charged magnetite particles during flotation separation from NaOL solutions.

Pyrrhotite (Fe 1-X S, 0 < x less than 0.223) has a high magnetism close to magnetite, so it is unlikely to separate pyrrhotite from magnetite in the magnetic separation process. Froth flotation as a physicochemical separation process is often adopted in the process of magnetite desulfurization (Agar, 1991, Yuan et al., 2022b).
