Iron-rich high-silicon copper tailing mineral admixture
The invention discloses an iron-rich high-silicon copper tailing mineral admixture which is prepared from iron-rich high-silicon copper tailing mineral slag, and the iron-rich high-silicon copper tailing mineral slag comprises 36.71-44.87 wt% of SiO2, 40.29-49.23 wt% of Fe, 8.02-9.79 wt% of Al2O3, 2.33-2.85 wt% of CaO, 1.04-1.28 wt% of MgO, 0.73-0.89 wt% of SO3, and 0.74-0.91 wt% of CuO. Accordingto the invention, the method comprises the following steps: drying the iron-rich high-silicon copper tailing mineral slag, uniformly mixing and stirring with a certain amount of coke powder and dolomite powder, carrying out pelletizing and drying, calcining and carrying out secondary magnetic separation in sequence. On one hand, iron in the copper tailing slag can be recycled, on the other hand,slag obtained after magnetic separation can be prepared into the copper tailing mineral admixture to serve as a substitute of fly ash in cement concrete and cement mortar, the production cost of the cement concrete is further reduced, the problem of environmental pollution is solved, iron in slag can be recycled, and meanwhile the return profit of the cement concrete is increased.
本发明公开了一种富铁高硅铜尾矿矿物掺合料，由富铁高硅铜尾矿渣制成，所述富铁高硅铜尾矿渣包含：SiO，36.71～44.87wt％；Fe，40.29～49.23wt％；AlO，8.02～9.79wt％；CaO，2.33～2.85wt％；MgO，1.04～1.28wt％；SO，0.73～0.89wt％；CuO，0.74～0.91wt％。根据本发明，其通过对富铁高硅铜尾矿渣进行烘干，与一定量焦粉、白云石粉混合拌匀，造球烘干后，先后经过煅烧及二次磁选后，一方面可对铜尾矿渣中的铁进行回收，另一方面可以将磁选后的渣料制成铜尾矿矿物掺合料，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，又能够对矿渣中的铁进行回收，同时还提高了水泥混凝土的回报利润。
