The invention discloses a method for preparing a spherical analcite mesoporous material from low-quality attapulgite clay tailings. The method is characterized in that through one-step hydrothermal reaction, the attapulgite clay tailings which are low in grade, complex in component and poor in adsorption property are transformed into a micron-grade spherical mesoporous adsorption material which is uniform and controllable in aperture distribution and excellent in adsorption property. On the premise that an organic surfactant type pore-forming agent is not introduced, the crystal structure and the aggregation state of attapulgite are transferred through one-step hydrothermal reaction, at the same time associated minerals are dissolved, crysatalized and recombined so as to obtain the mesoporous analcite material of the micron-grade spherical morphology, and the product is narrow in aperture distribution, simple in process, stable in product property, controllable in aperture distribution and excellent in adsorp
