The invention relates to the technical field of industrial solid waste treatment, in particular to a treatment method of ardealite solid waste, which comprises the following steps: mixing ardealite solid waste particles with limestone particles to obtain a particle mixture, and mixing and grinding the mixture in a dry-process pulverizer to produce weakly acidic ardealite mixed powder. According to the invention, an acid-base neutralization mechanism is taken as a main line, the ardealite solid waste is directly mixed and ground with limestone particles, the acidity of the ardealite solid waste is effectively reduced, the weakly acidic ardealite mixed powder is produced, the ardealite mixed powder is suitable for production and utilization in multiple industries, washing and calcining processes are omitted, and the production cost is reduced. The process flow of phosphogypsum solid waste treatment is greatly simplified, the production and equipment maintenance cost is greatly reduced, the utilization rate of the phosphogypsum solid waste is effectively increased, the additional value is increased, the production process is green and environment-friendly, and the industrial utilization of the phosphogypsum solid waste is greatly promoted.
本发明涉及工业固体废料处理技术领域，具体为一种磷石膏固体废料的处理方法，将磷石膏固体废料颗粒与石灰石颗粒混合得到的颗粒混合料，将混合料在干法磨粉机内进行混合研磨，生产出弱酸性的磷石膏混合粉料。本发明以酸碱中和机制为主线，将磷石膏固体废料直接与石灰石颗粒进行混合研磨，有效地降低磷石膏固体废料的酸性，生产出弱酸性的磷石膏混合粉料，适合于多个行业生产利用，省去了水洗、煅烧工艺，极大地简化了磷石膏固体废料处理的工艺流程，大幅降低了生产及设备维护成本，有效地提高磷石膏固体废料的利用率，提高附加值，生产过程绿色环保，对磷石膏固体废料的产业化利用起到极大的促进作用。
