Large-dosage copper tailing-based masonry cement and preparation method thereof
The invention provides high-dosage copper tailing-based masonry cement and a preparation method thereof, and relates to the field of solid waste disposal. The high-dosage copper tailing-based masonry cement is prepared from the following raw materials: 60% of cement clinker, 10% of limestone, 10% of gypsum and 20% of fly ash, wherein the limestone part in the large-dosage copper tailing-based masonry cement is replaced by the copper tailings; part or all of the fly ash is replaced by a copper tailing mixed material; the cement clinker is obtained by mixing and calcining limestone, clay, iron ore powder and coal gangue, and the iron ore powder is partially replaced by copper tailings; the copper tailing mixed material is obtained by grinding copper tailings and a modifier. The preparation method of the high-dosage copper tailing-based masonry cement comprises the following steps: mixing the raw materials, and carrying out ball milling to obtain the high-dosage copper tailing-based masonry cement. According to the high-dosage copper tailing-based masonry cement provided by the invention, the dosage of the copper tailings in the masonry cement can be greatly increased, and the production cost of a cement enterprise is reduced while reduction, value increase and consumption of the copper tailings are realized.
本申请提供一种大掺量铜尾矿基砌筑水泥及其制备方法，涉及固体废弃物处置领域。大掺量铜尾矿基砌筑水泥，其原料包括：水泥熟料60%、石灰石10%、石膏10%和粉煤灰20%；其中，大掺量铜尾矿基砌筑水泥中的石灰石部分用铜尾矿替代；粉煤灰部分或全部用铜尾矿混合材替代；水泥熟料由石灰石、粘土、铁矿粉、煤矸石混合、煅烧得到，其中，铁矿粉部分用铜尾矿替代；铜尾矿混合材由铜尾矿和改性剂粉磨得到。大掺量铜尾矿基砌筑水泥的制备方法，包括：将所述原料混合，球磨得到所述大掺量铜尾矿基砌筑水泥。本申请提供的大掺量铜尾矿基砌筑水泥，可大幅度提高铜尾矿在砌筑水泥的用量，实现铜尾矿减量化增值消纳的同时降低水泥企业生产成本。
