Abstract: Incorporating characteristics and arrangements of dry-tailing stacking and dry stockpile,dry-tailing stacking systems engineering were carried into execution in iron ore mineral processing plant.Main influence factors of dry stockpile's stability were systematically discussed.Subsequently,some suggestions and methods have already been put forward,how to supervise and manage dry stockpile of mineral processing tailing.Over two years production practice have indicated that the dry-tailing stacking and dry stockpile according to their properties possesses high safety and reliability,particular qualitative practicability and can obtain good economic benefits,as well as a good application prospect.
