Filling method for preparing sulfuric acid from ardealite and co-producing mine filling gel
The invention discloses a filling method for preparing sulfuric acid from ardealite and co-producing mine filling gel, the adopted raw materials comprise ardealite clinker and other materials, the weight ratio of the ardealite clinker to the other materials is 1: (4-10), and the other materials refer to tailings and barren rock; sulfur dioxide generated after ardealite is heated and subjected to high-temperature decomposition is used for preparing sulfuric acid, and residual waste residues are ardealite clinker. The filling and mining cost of the mine can be reduced, meanwhile, pollution of phosphogypsum accumulation to the surface environment is reduced, resource utilization of phosphogypsum is promoted, resource waste is avoided, and safe and efficient mining of the mine is guaranteed.
本发明公开了一种磷石膏制硫酸联产矿山充填胶凝充填方法，采用的原料包括磷石膏熟料和其他材料，磷石膏熟料和其他材料的重量比是1：4至10，所述其他材料指的是尾矿和废石；将磷石膏加热进行高温分解后产生的二氧化硫用于制取硫酸，剩余的废渣就是磷石膏熟料。本发明不仅可降低矿山充填开采成本，同时有利于减小磷石膏堆积对地表环境的污染，推动磷石膏资源化利用，避免资源浪费，保障矿井安全高效开采。
