| titleOfInvention | A kind of high-energy grinding preparation of rare earth-loaded bentonite and its preparation method |
| abstract | The invention provides a high-energy grinding preparation of rare earth loaded bentonite and a preparation method thereof, and relates to the technical field of preparation methods of rare earth loaded bentonite. A preparation method for preparing rare earth-loaded bentonite by high-energy grinding, comprising: placing bentonite in a high-energy ball mill for grinding, and obtaining weakly crystalline bentonite after the grinding is completed; putting the weakly crystalline bentonite into a multi-rare earth solution to stir; stirring After completion, perform plate and frame filtration, and then repeat the stirring operation again. After the stirring is completed, plate and frame filter, wash with water, and dry to obtain rare earth-loaded bentonite. The invention reduces the particle size of the bentonite through high-energy grinding, and at the same time, its crystal structure is partially destroyed to form a weakly crystalline bentonite, which is more conducive to the subsequent preparation of the rare earth-loaded bentonite. |
