Bleaching clay, also known as bleaching earth, is used in oil refining to absorb color pigments, impurities, and trace metals from oils. The clay has high surface area and adsorptive properties, making it effective in removing unwanted substances from oils. It is typically mixed with oil at elevated temperatures to maximize contact and adsorption efficiency.
