Foamed ceramic terrazzo composite board and preparation method thereof

The invention provides a foamed ceramic terrazzo composite board and a preparation method thereof. The preparation method comprises the following steps: putting 40% of iron tailing powder, 40% of perlite tailings, 19.6% of kaolin and 0.4% of a foaming agent into a ball mill; adding water and high-aluminum grinding balls according to a weight ratio of the balls to powder to water of 1.6: 1.0: 0.6,then adding sodium tripolyphosphate accounting for 0.5% of the total weight of the powder, and conducting ball milling for 6 h; putting a mixture for foamed ceramic into a refractory mold; putting therefractory mold on a kiln car table board of a tunnel kiln or a roller bar of a roller kiln, conducting firing at a high temperature of 1180 DEG C for 0.5 hour, and carrying out quick cooling to roomtemperature; pouring cement, mineral pigment accounting for 3%-6% of the weight of the cement and stone particles into a terrazzo machine for mixing; and placing sealing partition plates on the periphery of a foamed ceramic pa
