[0025] Example 1
[0026] Prepare product A: Put the clay ore into the crusher for rough crushing to obtain product A;
[0027] Preparation of ore slurry: adding water, dispersant and product A into a ball mill at a mass ratio of 30:0.15:69.85, and ball milling and beating to obtain a slurry;
[0028] Preparation of activated clay: Put the pulp into the reaction tank, add 65% sulfuric acid, and activate it for 40 minutes at a temperature of 85°C and a rotation speed of 100 revolutions / min. The mass ratio of the pulp and acid is 100:2.5. After activation, it is washed with water, Press filtration, drying and crushing to obtain activated clay;
[0029] Preparation of the impurity removal and decolorization composition: the activated clay, anhydrous inorganic salt and the adsorbent are uniformly mixed in a mass ratio of 87:3:10 to obtain the impurity removal and decolorization composition.
