| titleOfInvention | Method for extracting ion adsorption type rare earth |
| abstract | A method for extracting ion-adsorption type rare earth comprises using calcium chloride and aluminum sulfate solution as leaching agent, leaching ion-adsorption type rare earth in two main stages, and neutralizing tailings with calcium hydroxide solution to achieve multiple targets of no ammonification, high efficiency, stable tailings, etc.; the method solves the problems of insufficient leaching efficiency when calcium chloride is singly used and difficult subsequent rare earth separation when aluminum sulfate is singly used, the zeta potential absolute value of clay minerals in the leaching process can be close to the original value so as to prevent water and soil loss and landslide risk caused by clay particle loss, the pH value of tailing leaching water reaches more than 6 so as to meet the standard discharge requirement of pollutants, and the green and efficient leaching of ion adsorption type rare earth is realized. |
