METHOD AND DEVICE FOR MANAGEMENT AND TREATMENT OF FLUID TAILINGS IN TAILINGS POND

摘要

This invention discloses a method and relevant devices for management andtreatment of fluidtailings, and in-situ deposition of the treated tailings within a tailingspond, as well as simultaneousreclamation of the tailings pond. The method of the invention comprises: a)using a floating dyke todivide a tailings pond into two sections, b) using one of the sections tocollect the runoff fluidtailings, c) using a floating divider and combining with the other side of thefloating dyke to form abottomless thickener for treatment of fluid tailings, in-situ deposition ofthe treated tailings, andbuilding up an under-water beach from the treated tailing deposits, and d)relocating the floatingdyke and the floating divider downstream to build up a new dividing andtreatment system after theunder-water-beach meets the reclamation requirements, and developing a newabove-water-beach tocover the under-water-beach for tailings pond reclamation. The invention alsoprovides relevantdevices for using the said method.
