Abstract

The invention relates to a low cost ceramic floor tile and a preparation method, the ceramic floor tile comprises the following raw materials by weight percentage: 20-25% of bayer process red mud, 20-25% of ferrochrome slag, 8-12% of felsites-type gold ore tailings, 8-12% of fly ash, 8-12% of fluidized bed oven slag, 10-15% of talcum and 10-15% of quicklime. The ceramic floor tile provided by the invention takes red mud and fluidized bed oven slag as main raw materials, and the red mud and fluidized bed oven slag substitute the rare kaolin with high cost and high quality, so that dependence of ceramic industry in our country to kaolin is reduced, and crisis of high-quality kaolin scarcity due to rapid development of industry can be alleviated.

Description

technical field [0001] The invention relates to the technical field of manufacturing ceramic floor tiles, in particular to a low-cost ceramic floor tile and a manufacturing method thereof. Background technique [0002] The annual discharge of red mud in my country is close to 7 million tons. The composition of red mud changes greatly, and the harmful components are many and difficult to control. The recovery and reuse of red mud has always been in the stage of laboratory research. Ferrochromium slag piled in the open air after a long time in the slag yard turned into Cr 6+ , pollute the soil and groundwater, and cause great harm to human, animal and plant health. In recent years, in order to improve the conversion efficiency of coal-fired power plants, domestic thermal power plants have adopted circulating fluidized bed combustion technology to produce fly ash with high calcium oxide and alumina content. Efficient treatment of this kind of high-calcium fly ash has become a...
