Harmless resource utilization method of cyaniding gold extraction tailing slag
The invention discloses a harmless resource utilization method of cyaniding gold extraction tailing slag, and relates to the field of resource recycling. The harmless resource utilization method of cyaniding gold extraction tailing slag comprises the following steps: mixing gold tailing slag, Laiyang soil, refractory clay, calcined talc, calcite, dolomite, flint clay, alumina, diopside and potassium-sodium feldspar in proportion to form a batch mixture; adding the batch mixture, sodium tripolyphosphate accounting for 0.25-0.35% of the mass of the batch mixture and water accounting for 0.8-1 time the mass of the batch mixture into a ball mill, grinding until 250-mesh screen residues of the slurry are less than 0.5%, performing spray drying granulation, pulverizing, performing compression molding to obtain a green brick, and firing the green brick at 1100-1120 DEG C for 90-105 minutes. According to the harmless resource utilization method for the cyaniding gold extraction tailing slag, the gold tailing slag is matched with other mineral raw materials and chemical reagents to be subjected to the technological processes of mixing, forming, drying, firing and the like to obtain a product meeting the technical standard of building materials, so that a large amount of harmless utilization of the cyaniding tailing slag is achieved.
一种氰化提金尾矿渣无害资源化利用方法，涉及资源回收利用领域。该氰化提金尾矿渣无害资源化利用方法是将金尾矿渣、莱阳土、耐火粘土、煅烧滑石、方解石、白云石、焦宝石、矾土、透辉石、钾钠长石按比例混合成配合料；将配合料、配合料质量0.25‑0.35％的三聚磷酸钠和配合料质量0.8‑1倍的水加入球磨机中，磨至浆料250目筛余在0.5％以内，喷雾干燥造粒、制粉、压制成型得到砖坯，将砖坯在1100‑1120℃之间烧制90‑105min。本实施例提供的氰化提金尾矿渣无害资源化利用方法将金尾矿渣配合其他矿物原料和化学试剂经混合、成型、干燥、烧成等工艺过程得到符合建筑材料技术标准的产品，从而实现了氰化尾渣的大量无害化利用。
