Household ceramic produced by comprehensively utilizing various tailings and manufacturing method thereof

The invention discloses a household ceramic manufacturing method. The blank of the household ceramic is prepared from the following raw materials in percentage by weight: 18 to 20 percent of Chengkeng clay tailing, 15 to 17 percent of Guodong china clay tailing, 19 to 22 percent of Tudike kaolin tailing, 16 to 17 percent of feldspar and 24 to 27 percent of clay. The manufacturing method comprises the following steps of: screening the Chengkeng clay tailing, the Guodong china clay tailing and the Tudike kaolin tailing according to classes, removing impurities, crushing, mixing according to a proportion, performing ball milling, sieving, iron removal, pressure filtration, coarse refining, ageing, and vacuum pugging to obtain a blank, drying, and glazing; and firing to obtain the household ceramic finished product. Various tailings are compounded, and the tailings account for 52 to 59 percent of the total mass of the raw materials. The household ceramic has the advantages of low production cost, high finished pr
