Description

B03C covers separation technologies employing magnetic fields, electrostatic forces, or high-voltage electric fields to segregate solid materials from other solids or fluids. This subclass encompasses magnetic separators (permanent magnet and electromagnet-based systems), electrostatic separators, and corona-discharge or high-voltage techniques for particle classification and purification. Applications include mineral processing, recycling of electronic waste and metals, food processing contaminant removal, and industrial ore beneficiation. Separation methods relying on density differences using liquids or pneumatic equipment are excluded, falling instead under other B03 subclasses.
