Embodiment 1

[0046] The preparation of embodiment 1 ceramic floor tile

[0047] 1) Mixing of raw materials

[0048] Proportion by mass: 55% copper-molybdenum tailings, 29% diopside, 6% feldspar, 10% Laiyang, put the mixed raw materials into a ball mill, and add 0.8% of the mass of copper-molybdenum tailings CaCO 3 Mix with water until the raw material concentration is 40%, grind to 4% remaining on the million-hole sieve, spray dry, and set aside;

[0049] 2) Dry the above materials to a moisture content of 7%;

[0050] 3) Using an automatic hydraulic molding machine to press the material obtained in step 2) with a strength of 25 MPa to obtain an embryo body;

[0051] 4) The embryo body obtained in step 3) is dried in a roller-type drying kiln at 110±5°C and then glazed, and then sintered in a roller-type kiln at 1160°C×23min to obtain ceramic floor tiles.

[0052] It has been determined that the flexural strength of ceramic floor tiles is 1402.6N, the modulus of rupture is 44.45MP, and ...

Abstract

The invention relates to a constructional ceramic prepared from copper-molybdenum tailings. The ceramic is composed of the following components in parts by weight: 20 to 70 parts of copper-molybdenum tailings, 10 to 35 parts of diopside, 10 to 40 parts of Laiyang soil, and 0 to 10 parts of feldspar. The added tailing can account for 70% of the weight of ceramic wall tile and ceramic floor tile, the tailing is converted into valuable resources, the environment pollution is avoided, the environment is protected, the ceramic raw material shortage is relieved, and the production cost for the ceramic industry is reduced.

Description

technical field [0001] The invention relates to building ceramics prepared by using copper-molybdenum tailings and a preparation method thereof, belonging to the field of mineral processing. Background technique [0002] In our country, 95% of energy and 85% of raw materials come from mineral resources. When mineral resources are developed and utilized, a large amount of tailings will be produced. According to statistics, by the end of 2013, there were a total of 12,273 tailings ponds, of which 6,633 were in use, 1,234 were under construction, 2,193 were closed, and 2,213 were out of service. At present, the accumulative stockpile of tailings in my country is about 12 billion tons, of which it reached 1.581 billion tons in 2011 and 1.8 billion tons in 2013. Under the existing technical conditions, most of these tailings are piled up in tailings ponds. [0003] However, there are a large number of valuable components (metals and non-metallic minerals) that have not been rec...
