| titleOfInvention | Iron tailing baked brick and preparation method thereof |
| abstract | The invention discloses an iron tailing baked brick and a preparation method thereof. The iron tailing baked brick is prepared from the following raw materials in parts by mass: 49-59 parts of iron tailings; 24-30 parts of fly ash; 11-27 parts of sulfur-containing sludge in a mine drainage plant. The iron tailing sintered brick is prepared by sintering tailings produced by mineral separation, sludge discharged from a water plant outside a mine and fly ash under a specific raw material proportion, the compressive strength of the iron tailing sintered brick obtained through the synergistic effect of the components is more than 10MPa, the bulk density is 1600-1800 kg/m, the water absorption rate is less than 20%, the concentration of heavy metal in leachate is far lower than a specified threshold value, and sulfur in sludge can be fixed, so that harmless and resource utilization of mine field waste is realized. |
