    Whole Tailings Cement-filling System
    Sunny made it possible to use mine tailings and waste rock economically and efficiently to eliminate hazards. The Sunny whole tailings cement -filling technology utilizes whole tailings as aggregate and uses cementing powder instead of cements, prepares filling paste slurry with strong activation stirring and sends high-concentration full tail cement paste slurry into the goaf by the pipe self-propelled conveying and pumping process to form a stable homogeneous structure of the backfill supporting rock formations. Thanks to the high utilization rate of tailings, the mine has achieved "no waste" production and the problem of selecting construction site that troubled the mine has been solved, too. The success of this technology has made it possible to build mines with no tailings ponds or tailings, provided valuable technology for mine environment planning and treatment and produced huge economic benefits. Sunny thickly dehydrates all whole tailings, making the whole tailings a paste. The whole tailing paste is metered and fed to a forced mixer, and the cement is added to the mixer. After the other aggregates are adjusted in concentration, the paste is prepared into paste filler. Then fill the paste filler by pressurizing it with hydraulic double-cylinder piston pump or conveying it down-hole through the natural pressure head, the filling hole and the down-hole pipe networks. High-quality filled tailings do not need to be graded and rushed down-hole and it can protect the surface of the mining area and reduce or avoid the land occupied by tailings and effectively protect the mining area and its surrounding ecological environment. It also provides good conditions for mining operations in order to maximize the recovery of ore resources to achieve the maximum economic benefits and good social and environmental benefits of the mine.
