文摘Based on the systematic experiment of treating low concentration lye in the red mud mound, several key problems in the selection of technological process for industrial trial, such as aluminum precipitation in the process of electrodilalysis, dealuminum with carbon dioxide at low temperature, the selection of the technology for electrodialysis and estimation of benefit of the trial production line, are studied in the paper. For a production line with the handling capacity of 50 m 3/h, its annual direct economic benefit can reach RMB 4 million yuan, calculated by 300 working days a year.
