Comprehensive recycling process for zinc-indium-containing gypsum slag
The invention discloses a zinc-indium-containing gypsum slag comprehensive recycling process which comprises the following steps: S1, washing zinc-indium-containing gypsum slag with a washing solution to obtain washed gypsum slag and the washing solution; s2, a neutralizing agent is added into the washing liquid, and neutralized indium precipitation residues and neutralized indium precipitation liquid are obtained; s3, drying the washed gypsum residues to obtain a gypsum powder filler; s4, mixing and uniformly stirring the gypsum powder filler, the fine aggregate, the coarse aggregate, the self-luminous material, the cement and the water in parts by weight, and filling a mold with the mixture to prepare a kerb blank; and S5, the kerb blank is put into a belt type sintering machine to be sintered, and the kerb with the good light-emitting performance is obtained. On the basis that zinc and indium are recycled through acid pickling, neutralization and sediment, the light-emitting curb is manufactured through the gypsum powder filler, the powder filler contains zinc and indium, the prepared curb is better in light-emitting effect and can replace a traditional cementing material, the problem of recycling of the zinc-indium gypsum residues is solved, and a new technical scheme is provided for recycling of the zinc-indium gypsum residues.
本发明公开了一种含锌铟石膏渣综合回收利用工艺，包括：S1：将含锌铟石膏渣通过洗涤液洗涤，得到洗涤后的石膏渣、洗涤液；S2：将洗涤液加入中和剂，得到中和沉铟渣、中和沉铟液；S3：将洗涤后的石膏渣烘干，获得石膏粉状填料；S4：将石膏粉状填料：细骨料：粗骨料：自发光材料：水泥：水按重量份比混合并搅拌均匀，并填入模具中制成路缘石坯；S5：将路缘石坯放入带式烧结机中烧结，得到发光性能良好的路缘石。本发明在酸洗中和沉渣回收锌和铟的基础上，用石膏粉状填料制作发光路缘石，粉状填料中含有锌和铟，制备的路缘石发光效果更好，可以代替传统胶凝材料，不仅解决锌铟石膏渣回收再利用的问题，还为锌铟石膏渣再利用提供新技术方案。
