Molybdenum tailing powder artificial aggregate and preparation method and application thereof
The invention discloses a molybdenum tailing powder artificial aggregate as well as a preparation method and application thereof, which are used for solving the problem of resource utilization of molybdenum tailings. The molybdenum tailing powder artificial aggregate is composed of a powder component and a liquid component, and the liquid component is 15-35 w parts of the powder component; the powder component comprises the following components in per cubic meter of the artificial aggregate: 50-70 parts of molybdenum tailing powder, 10-25 parts of cement, 3-12 parts of slag powder and 5-10 parts of silica fume; the liquid component is prepared from the following components in parts by weight: 35 to 55 parts of water glass, 2.5 to 4.5 parts of sodium hydroxide, 0.2 to 0.5 part of a water reducing agent and 40 to 65 parts of water. The molybdenum tailing powder is used as a main component, and is mixed with the cement, the slag powder and the silica fume to form the spherical aggregate under the adhesion action of the liquid component, so that the resource utilization of the molybdenum tailings is realized by the obtained aggregate, and the pollution to the environment is reduced. The invention further provides a preparation method and application of the molybdenum tailing powder artificial aggregate, the molybdenum tailing powder artificial aggregate can be used as a raw material of concrete, and resource utilization of the molybdenum tailings is achieved while the strength of the concrete is guaranteed.
本发明公开了一种钼尾矿粉人造骨料及其制备方法和应用，用于解决钼尾矿的资源化利用的问题。一种钼尾矿粉人造骨料，由粉料组分和液体组分组成，所述液体组分为所述粉料组分的15‑35w份；以每立方米人造骨料计，所述粉料组分包括以下组分：钼尾矿粉50‑70份、水泥10‑25份、矿渣粉3‑12份、硅灰5‑10份；所述液体组分包括以下组分：水玻璃35‑55份、氢氧化钠2.5‑4.5份、减水剂0.2‑0.5份、水40‑65份。钼尾矿粉为主要组分，与水泥、矿渣粉、硅灰混合并在液体组分的黏粘作用下形成球状骨料，得到的骨料解决了钼尾矿的资源化利用，减少对环境的污染。还提供了一种钼尾矿粉人造骨料的制备方法和应用，可作为于混凝土的原料，在保障混凝土强度的同时达到钼尾矿的资源化利用。
