Ceramic tile preparation method and ceramic tile

The invention provides a ceramic tile preparation method and a ceramic tile, and the ceramic tile preparation method comprises the following steps: proportioning raw materials in a blank formula according to a predetermined proportion to obtain a mixture, the raw materials in the blank formula comprising raw ore bentonite; carrying out first ball milling treatment on the mixture to obtain first slurry; adding sodium carbonate into the first slurry, and carrying out second ball milling treatment to obtain second slurry; and drying and granulating the second slurry to obtain powder, carrying out compression molding treatment on the powder to obtain a green body, and treating the green body to obtain the ceramic tile. According to the invention, sodium carbonate is added in the ball milling process to modify the raw ore bentonite in the blank formula, and sodium carbonate is added into a ball mill before ball stopping instead of other raw materials, so that the grinding time is prevented from being too long to r
