Iron tailing powder activity improving method and application thereof
The invention discloses an iron tailing powder activity improving method and application thereof, and relates to the technical field of iron tailing activating treatment. The method comprises the following steps: drying, uniformly mixing and grinding sieved iron tailing powder, lime, steel slag powder I and gypsum; adding a microwave exciting agent, continuously stirring uniformly, and carrying out microwave heating treatment to improve the activity of the iron tailing powder; the microwave exciting agent comprises the following raw materials: 90-95 wt% of steel slag powder II, 1-3 wt% of silicon carbide and 2-7 wt% of ferrous oxide. According to the method, a mechanical-chemical-microwave multi-dimensional coupling activation mode is utilized, and compared with conventional mechanical activation, chemical activation and other modes, the activity of the iron tailings is further improved, so that the activated active iron tailing powder can replace a considerable part of cement to be used in concrete and other building materials.
本发明公开了一种铁尾矿粉活性提升方法及其应用，涉及铁尾矿活化处理技术领域。本方法包括以下步骤：将过筛后的铁尾矿粉，以及石灰、钢渣粉Ⅰ、石膏干燥，混匀和粉磨；加入微波激发剂后继续搅拌均匀，微波加热处理，完成铁尾矿粉的活性提升；微波激发剂的原料包括钢渣粉Ⅱ90‑95wt％、碳化硅1‑3wt％和氧化亚铁2‑7wt％。本方法利用机械‑化学‑微波多维耦合活化的方式，相比于常规的机械活化和化学活化等方式而言，进一步提升了铁尾矿的活性，使得活化后的活性铁尾矿粉能够替代相当一部分水泥用于混凝土等建筑材料中能够。
