Soluble impurity remover in ardealite and preparation method thereof
The invention relates to the technical field of preparation of an ardealite impurity remover, in particular to a soluble impurity remover in ardealite and a preparation method of the soluble impurity remover. Comprising the following steps: obtaining waste concrete, and sequentially carrying out crushing, calcining, rapid cooling and ball milling processes on the waste concrete to obtain a mechanical mixture of recycled aggregate and hardened cement stone fine powder; the mechanical mixture is screened, and hardened cement stone fine powder with the small particle size is collected; grinding the hardened cement stone fine powder to obtain a ground sample, and carrying out magnetic separation iron removal on the ground sample to obtain the soluble impurity remover in the phosphogypsum; the waste concrete is used for preparing the soluble impurity remover in the ardealite, the effect of replacing or partially replacing calcium-containing agents or natural minerals is achieved, the green, environment-friendly and low-price remover is provided, high-value utilization of the waste concrete is achieved, and environmental protection is facilitated.
本发明涉及磷石膏杂质去除剂制备技术领域，具体涉及一种磷石膏中可溶性杂质去除剂及其制备方法；包括以下步骤：获取废弃混凝土，并对废弃混凝土依次进行破碎、煅烧、快冷和球磨工艺，获得再生骨料和硬化水泥石细粉的机械混合物；将机械混合物进行筛分，并收集粒径较小的硬化水泥石细粉；对硬化水泥石细粉进行粉磨，获得粉磨样品，并对粉磨样品进行磁选除铁，获得磷石膏中可溶性杂质去除剂；将废弃混凝土制备出磷石膏中可溶性杂质去除剂，起到替代或部分替代含钙药剂或天然矿物的作用，提供了一种绿色环保且价格低廉的去除剂，并高值化利用废弃混凝土，有利于环境保护。
