A method for producing activated bentonite comprises the bentonitic mixing, extraction from it of non-clay impurities, batching of bentonitic clay and its processing with activating agent at stirring with further drying to 10-17 % of moisture. HSOsulfate acid is used as activating agent in the form of 20 – 30 % solution. The mixing, extraction of non-clay impurities, processing with activating agent and stirring are carried out simultaneously in porcelain grinding mill, and bentonite is washed before drying. |
