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.
