Copper tailing mineral admixture
The invention discloses a copper tailing mineral admixture. The copper tailing mineral admixture is prepared from copper tailing slag. The copper tailing slag comprises the following components in percentage by mass: 50.64-69.91 wt% of SiO2, 13.79 wt% to 20.45 wt% of Al2O3, 6.05-10.34 wt% of Fe2O3, 3.04-4.79 wt% of K2O, 2.11-5.67 wt% of CaO, 1.27-2.13 wt% of MgO, 0.11-1.16 wt% of SO3, 0.18-0.26 wt% of Na2O, 0.13-0.16 wt% of CuO, and 0.01-0.03 wt% of Ag2O. According to the invention, the content of the copper tailing slag is increased, and the copper tailing slag is used as a substitute of flyash in cement concrete and cement mortar, so the production cost of the cement concrete is further reduced, the problem of environmental pollution is solved, and the return profit of the cement concrete is improved.
本发明公开了一种铜尾矿矿物掺合料，由铜尾矿渣制成，以质量百分比计，所述铜尾矿渣包含：SiO，50.64～69.91wt％；AlO，13.79～20.45wt％；FeO，6.05～10.34wt％；KO，3.04～4.79wt％；CaO，2.11～5.67wt％；MgO，1.27～2.13wt％；SO，0.11～1.16wt％；NaO，0.18～0.26wt％；CuO，0.13～0.16wt％；AgO，0.01～0.03wt％。根据本发明，其通过增加铜尾矿渣的含量，作为粉煤灰在水泥混凝土、水泥砂浆中的替代品，进一步降低了水泥混凝土的生产成本，既解决了环境污染问题，又提高了水泥混凝土的回报利润。
