Preparation method of lead-zinc tailing-based sintered brick and lead-zinc tailing-based sintered brick
The invention discloses a preparation method of a lead-zinc tailing-based sintered brick and the lead-zinc tailing-based sintered brick, and belongs to the field of recycling of tailings. The method comprises the following steps: uniformly mixing 89-94% by mass of a main body raw material and 6-11% by mass of glass powder to obtain a mixture; the main raw materials comprise lead-zinc tailings and clay, and the mass ratio of the lead-zinc tailings is greater than that of the clay; adding water into the mixture, and uniformly stirring to obtain a blank; the blank is placed in a sealing device and placed in a room temperature environment for a first preset duration, and an aged blank is obtained; sequentially carrying out pressure forming and drying on the aged blank to obtain a dried green brick; and sintering the dried green brick according to a preset sintering temperature model to obtain the lead-zinc tailing-based sintered brick. According to the preparation method of the lead-zinc tailing-based sintered brick, the mechanical property and strength of the lead-zinc tailing-based sintered brick are effectively improved, and meanwhile, the utilization rate of the lead-zinc tailings can be increased.
本申请公开了一种铅锌尾矿基烧结砖的制备方法及铅锌尾矿基烧结砖，属于尾矿循环利用领域。所述方法包括步骤：将质量占比89％～94％的主体原料与质量占比6％～11％的玻璃粉均匀混合得到混合料；主体原料包括铅锌尾矿和粘土，铅锌尾矿的质量占比大于粘土的质量占比；将水加入至混合料中搅拌均匀得到坯料；将坯料置入密封装置中并在室温环境下放置第一预设时长得到陈化好的坯料；将陈化好的坯料依次经过加压成型、干燥得到烘干后的砖坯：将烘干后的砖坯按照预设烧结温度模型烧结得到铅锌尾矿基烧结砖。通过本申请中的铅锌尾矿基烧结砖的制备方法，有效提高了铅锌尾矿烧结砖的力学性能和强度，同时也能增加铅锌尾矿的利用率。
