High-sulfur tailing resource utilization system and method based on microwave desulfurization recovery and residual sulfur excitation slag solidification
The invention discloses a high-sulfur tailing resource utilization system and method based on microwave desulfurization recovery and residual sulfur excitation slag solidification, and belongs to the technical field of metal mine tailing harmless utilization, and the system comprises a high-sulfur tailing dense dehydration system, a continuous microwave sulfide decomposition device and a low-sulfur ore pulp filling production system. On one hand, the method for generating instantaneous high-temperature desulfurization by using radiation microwaves not only can efficiently desulfurize and prepare acid and realize multi-level cyclic utilization of mine solid waste, but also can improve the early strength of the filling body and shorten the mining production period; on the other hand, residual sulfate after microwave desulfurization is utilized to excite the slag-based cementing material, so that low-cost and high-strength consolidation is realized.
基于微波脱硫回收与余硫激发矿渣固化的高硫尾砂资源化利用系统及方法，属于金属矿矿山尾砂无害化利用技术领域，包括高硫尾砂浓密脱水系统、可连续微波分解硫化物装置、低硫矿浆充填生产系统。本发明一方面，利用辐射微波产生瞬时高温脱硫的方法，不仅可以高效脱硫制酸，实现矿山固废多层次循环利用，还能提高充填体的早期强度，缩短了采矿生产周期；另一方面，利用微波脱硫后残余的硫酸盐激发矿渣基胶结料，实现了低成本高强度固结。
