Abstract

In order to apply the dry tailing stacking technology better and promote the development of the tailings disposal technology, the papers on the dry tailings disposal in the Database of Ei Compendex and Chinese Academic Periodical Full Text are searched and analyzed by using statistics methods, and based on the analysis, the application status and the research progress of the dry tailings disposal technology at home and abroad are reviewed, with examples, including the effects of the tailings concentration and the rainfall on the dry heaping of tails and the priciples, advantages and limitations of the dry tailings disposal. The domestic dry tailings disposal is compared with that in other countries. The present situation of the dehydration technology and the key technology of the dry tailings disposal are also reviewed. The tailings pressure filtration dehydration technology, the tailings thickening-pressure filtration/thickening-filtration dehydration technology and the tailings classifying-thickening- pressure filtration dehydration technology are considered as the three most commonly used dehydration technologies. The related dewatering equipment is briefly discussed. The technical and management issues on the current dry tailings disposal technology are analyzed. At last, the future prospect for the application of the dry tailings disposal is suggested.
