Microwave-assisted method for quickly whitening mixed-color mixed-dimensional attapulgite by utilizing microwave assistance

The invention discloses a microwave-assisted method for quickly whitening mixed-color mixed-dimensional attapulgite, which comprises the following steps: carrying out crushing and cyclone separation treatment on natural mixed-color mixed-dimensional attapulgite raw ore, conducting dispersing in a whitening preparation water solution to form ore pulp, stirring the ore pulp for 10-60 minutes, transferring the stirred ore pulp into a microwave reactor to carry out microwave treatment, and conducting washing, solid-liquid separation, and drying to obtain a white attapulgite product. By utilizing the characteristics of good penetrability and the like of microwave reaction and combining the reducibility and complexing property of the whitening preparation, the whitening of the mixed-color mixed-dimensional attapulgite can be quickly realized, and the whitening effect is good. Meanwhile, the attapulgite rod crystal structure and the lamellar structure of associated minerals are not damaged, the comprehensive charact
