High-silicon tailing-based cementing material
The invention discloses a high-silicon tailing-based cementing material, which comprises 55-65 wt% of high-silicon tailings and 35-45 wt% of a coagulation accelerating activator, the high-silicon tailings are tailings left after sulfur separation and enrichment of cyanidation tailings, and the coagulation accelerating activator comprises the following components in percentage by weight: 15-25 wt% of gypsum and 10-20 wt% of a reinforcing agent in the slag-based fine tailing cementing material. According to the material, the high-silicon tailings are used as main raw materials, comprehensive utilization of the cyanidation tailings can be achieved, waste is turned into wealth, and the cost is low; the raw materials used in the material are convenient to obtain, the preparation process is simple, sintering is not needed, the material can be obtained at normal temperature, and no waste gas or waste residue is discharged; the filling material can form better affinity with filling aggregate, is uniformly distributed in a filling body, can realize high-concentration conveying of filling slurry, and can realize mass filling of tailings.
本发明公开了一种高硅尾渣基胶凝材料，包括55‑65wt％的高硅尾渣和35‑45wt％的促凝激发剂，所述高硅尾渣为氰化尾渣选硫富集后所剩的尾矿，所述促凝激发剂各成分占所述矿渣基细尾胶凝材料的比例：石膏15‑25wt％、增强剂10‑20wt％。本发明中材料中以高硅尾渣为主要原材料，可实现氰化尾渣的综合利用，变废为宝，成本较低；材料中所用原材料获取方便，制备工艺简单，不用烧结，在常温下既可获得，无废气废渣排放；本发明与充填骨料能够形成较好的亲合力，在充填体中分布均匀，能够实现充填料浆的高浓度输送，可以实现尾砂的大量充填。
