Magnetic roasting iron ore dressing tailing ceramsite and preparation method thereof
The invention discloses magnetic roasting iron ore dressing tailing ceramsite and a preparation method thereof. The preparation method comprises the steps of drying and then mixing, in proportion, different types of magnetic roasting iron ore dressing tailings, then carrying out pretreatment , and obtaining a ball-milled initial mixture, wherein in the step 1, the different types of magnetizing roasting iron separation tailings comprise high-silicon type iron separation tailings, high-aluminum type iron separation tailings and high-calcium type iron separation tailings which are mixed in proportion; adding an additive and deionized water into the initial mixture, and uniformly stirring to obtain a ceramsite raw material; preparing ceramsite raw materials into raw material balls with the same size and uniform shape, wherein the diameter of each raw material ball is 10-15mm; carrying out drying treatment; then putting the materials into a high-temperature furnace for graded roasting; andcooling the raw material balls subjected to staged roasting along with the furnace to obtain the finished product of the magnetic roasting iron ore dressing tailing ceramsite. According to the technical scheme, the utilization rate of the magnetizing roasting iron separation tailings can be greatly increased, and then the influence of iron tailing accumulation on the environment is improved.
本发明公开一种磁化焙烧选铁尾矿陶粒及其制备方法,制备方法的步骤是:先将不同类型的磁化焙烧选铁尾矿烘干后按比例混合,然后进行预处理,得到球磨的初始混合料;所述步骤1中,不同类型的磁化焙烧选铁尾矿包括按比例混合的高硅型选铁尾矿、高铝型选铁尾矿、高钙型选铁尾矿;在初始混合料中加入添加剂和去离子水,搅拌均匀,得到陶粒生料;将陶粒生料制成大小相同、形状均匀的生料球,该生料球的直径为10‑15mm;再进行干燥处理;然后放入高温炉中进行分级焙烧;经过分级焙烧后的生料球随炉冷却即得到成品的磁化焙烧选铁尾矿陶粒。此种技术方案可大大提高磁化焙烧选铁尾矿的利用率,进而改善铁尾矿堆积对环境产生的影响。
