Porcelain tile
The invention discloses a porcelain tile prepared from 15-25% of clay, 15-70% of coal cinder, 10-55% of feldspar and 2-10% of additives according to a formula, wherein the coal cinder is pretreated through the following steps of (1) sieving the raw material of the coal cinder; (2) recovering iron in the coal cinder through magnetic separation equipment; (3) adding water into the coal cinder, and carrying out ball milling treatment on the coal cinder to obtain a first mixed material; (4) adding water into the coal cinder, and recovering iron powder through iron removal equipment to obtain a second mixed material; (5) adding a bleaching agent into the coal cinder, and carrying out sedimentation and bleaching treatment through a sedimentation tank; (6) carrying out filter pressing treatment on the coal cinder; and (7) drying the coal cinder to obtain coal cinder containing less than 0.5% of TiO2, less than 0.05% of V2O5 and less than 0.5% of Fe. By using the porcelain tile, the ball milling efficiency is increased, the iron removal effect is improved, the whiteness of a product is greatly improved, and the removed harmful substances can be recovered.
