Embodiment 1

[0049] First crush and screen the lead-zinc-copper tailings, quartz sand, calcite and nepheline; the fineness of the lead-zinc-copper tailings is above 40 mesh, the fineness of the calcite is above 80 mesh, and the fineness of the quartz sand is 60~ 80 mesh, the fineness of nepheline is 60-80 mesh, and the rest of the raw materials meet the national industry quality inspection standards. The cyanide in the lead-zinc-copper tailings is removed by ion exchange, and then weighed to make a mixture. The weight ratio of raw materials is: 70 parts of lead-zinc-copper tailings, 10 parts of quartz sand, 20 parts of calcite, and 5 parts of limestone, 4 parts of soda ash, 2 parts of zinc oxide, 4 parts of barium carbonate, 4 parts of borax, 2 parts of sodium nitrate, and 0.1 part of dicobalt trioxide. The purity of zinc oxide is 90%, the content of calcium oxide in calcite is 55.5%, the content of silicon oxide in quartz sand is 98%, the content of silicon in nepheline is 54%, and the co...

Embodiment 2

[0052] First crush and screen the lead-zinc-copper tailings, quartz sand, calcite and nepheline. The cyanide in the lead-zinc-copper tailings is removed by ion exchange, and then weighed to make a mixture. The weight ratio of raw materials is: 80 parts of lead-zinc-copper tailings, 8 parts of quartz sand, 10 parts of calcite, and 4 parts of limestone, 3 parts of soda ash, 1 part of zinc oxide, 2 parts of barium carbonate, 3 parts of borax, 2 parts of sodium nitrate, and 0.1 part of dicobalt trioxide. The color of the product is black.

[0053] The above-mentioned glass raw materials were melted in a glass tank furnace with a temperature of 1350° C. for 4 hours. After the melting was completed, the molten glass was directly poured into water to become glass pellets. 13 kg of glass granules were spread flat in a refractory mold with a size of 6000×9000 mm and crystallized in a shuttle kiln fueled by liquefied petroleum gas at a crystallization temperature of 1050°C. Thereby, a...

Embodiment 3

[0055]First crush and screen the lead-zinc-copper tailings, quartz sand, calcite and nepheline. The cyanide in the lead-zinc-copper tailings is removed by ion exchange, and then weighed to make a mixture. The weight ratio of raw materials is: 85 parts of lead-zinc-copper tailings, 5 parts of quartz sand, 8 parts of calcite, and 3 parts of limestone, 2 parts of soda ash, 1 part of zinc oxide, 2 parts of barium carbonate, 3 parts of borax, 2 parts of sodium nitrate, 0.1 part of dicobalt trioxide. The color of the product is black.

[0056] The above-mentioned glass raw materials were melted in a glass tank furnace with a temperature of 1350° C. for 4 hours, and after the melting was completed, the molten glass was directly flowed into water to become glass pellets. Spread 50 kg of glass granules flat in a refractory mold with a size of 6000×9000 mm and carry out crystallization in a shuttle kiln fueled by liquefied petroleum gas at a crystallization temperature of 1050°C. Ther...

Abstract

The invention relates to a black micro-crystal glass plate manufactured from lead-zinc-copper tailings, which is manufactured from the following raw materials in parts by weight: 60-90 parts of lead-zinc-copper tailings, 5-10 parts of quartz sand, 8-20 parts of calcite, 3-7 parts of nepheline, 2-4 parts of soda, 1-6 parts of zinc oxide, 2-8 parts of barium carbonate, 2-5 parts of borax, 2-6 parts of sodium nitrate and 0.1-0.5 part of cobalt oxide. The manufacturing method of the black micro-crystal glass plate comprises the following steps: grinding the lead-zinc-copper tailings, the quartz sand, the calcite and the nepheline into powder; removing cyanides from the lead-zinc-copper tailings by using an ion exchange method; weighing in proportion and preparing into a mixture; melting at 1250 DEG C-1350 DEG C; pouring the mixture into water for water quenching to obtain glass particles; horizontally laying the glass particles into a fire-resistant mold for crystallization treatment; and grinding and cutting black micro-crystal glass samples. The invention can relieve the harm of the tailings to the environment, reduce the cost of raw materials, and improve the product quality.

Description

technical field [0001] The invention relates to a glass-ceramic and a method for manufacturing the glass-ceramic. Background technique [0002] Glass-ceramic is a polycrystalline material obtained by controlling the crystallization of glass. At present, glass-ceramics has formed a special category of materials, with various varieties and different properties, and has a very wide range of uses. Glass-ceramic plate is one of many varieties of glass-ceramics. It is a new type of high-grade building decoration material with high strength, wear resistance, corrosion resistance, weathering resistance, non-absorbent, easy cleaning and maintenance, and no radioactive pollution. Features and uniform color tone, soft and crystal-clear luster, dense and flawless surface and other excellent appearance characteristics. Because the properties of the glass-ceramic plate are superior to natural stone in all aspects, it has been widely used in high-end decoration projects such as interior ...
