[0019] According to the mass ratio of 1:3, put wollastonite and anorthite into a ball mill, add steel balls with a diameter of 100 mm that are 4 times the mass of anorthite, and ball mill for 2 hours at 300 r / min to collect the ball milling mixture. According to a mass ratio of 1: 4. Put the ball mill mixture and sulfuric acid solution with a mass fraction of 70% into a container, heat the container in a microwave oven, heat it to 90°C, and keep it warm for 3 hours; after the above heat preservation is completed, add the above ball mill into the container respectively Water with twice the mass of the mixture, polyvinylpyrrolidone with 20% mass of the above-mentioned ball-milled mixture, and oxalic acid with 3% mass of the above-mentioned ball-milled mixture, after stirring evenly, continue to keep warm for 30 minutes, then put the mixture in the container into the reaction kettle, set the temperature 130°C, pressure 1.2MPa, heat preservation 6h; after the above heat preservatio...
