Method for detoxifying lepidolite acid leaching waste residues

The invention provides a lepidolite acid leaching waste residue detoxification method, which comprises: mixing lepidolite acid leaching waste residue with an antidote, carrying out ion exchange under an acidic condition to obtain a solid-liquid mixed material, and carrying out solid-liquid separation on the solid-liquid mixed material to obtain lepidolite detoxified residue, the antidote comprises an aluminum salt solution and/or an iron salt solution; according to the method, deep detoxification of the lepidolite acid leaching waste residues is achieved, the content of soluble thallium and the content of soluble beryllium in the detoxified residue leachate after detoxification are both as low as 5 micrograms/L or below, meanwhile, other metal salts are leached out, and reduction of the lepidolite acid leaching waste residues and resource utilization of valuable metal elements are achieved. 本发明提供一种锂云母酸浸废渣解毒的方法，所述方法包括：将锂云母酸浸废渣与解毒剂混合，并在酸性条件下进行离子交换得到固液混合物料，再将所述固液混合物料进行固液分离得到锂云母解毒渣；所述解毒剂包括铝盐溶液和/或铁盐溶液；本发明所述方法实现了锂云
