They are also weakly magnetic. However, if their magnetic susceptibilities are smaller than those of the iron minerals in oxidized iron ores, it is still possible to partially remove them from oxidized iron ores by magnetic separation. Low-grade iron ore mined from the earth is usually composed of several minerals, desirable and undesirable.

While the primary separating force in electrostatic separation is the electrical force (Eq. 6), particles are usually also subjected to a significant secondary force, that of drag [15]. For most practical conditions particles moving in afluid can be considered to accelerate immediately to move at a constant velocity, known as the terminal velocity.
