CPC Subclass Not Allocatable
B03C MAGNETIC OR ELECTROSTATIC SEPARATION OF SOLID MATERIALS FROM SOLID MATERIALS OR FLUIDS; SEPARATION BY HIGH-VOLTAGE ELECTRIC FIELDS (separating isotopes B01D59/00; combinations of magnetic or electrostatic separation with separation of solids by other means B03B, B07B)
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.
