how is iron ore from minerals such as magnetite separated magnetic separation

According to the different types of iron-bearing minerals, magnetite can be divided into single magnetite and mixed ore. In general, single magnet ore is often selected by weak magnetic separation method, and multi-metal magnet ore and mixed ore are usually combined process of multiple beneficiation methods
