Embodiment Construction
[0013] In the alkaline solution containing molybdenum and aluminum, add sodium hydroxide solution to adjust the free alkali concentration; according to the aluminum content of the solution and Al:Si (molar ratio), under stirring at 80rpm, add sodium silicate solution at a uniform speed; After crystallization and crystallization, filter with a centrifuge; the filter cake is stirred and washed with 500mL tap water at 26°C for 30 minutes and then centrifugally filtered to control the moisture content of the filter cake within 20%, and the filtrate is a molybdate solution. The specific technical scheme is shown in Table 1; the obtained results are shown in Table 2.
