Abstract: With the tailings from Sinosteel Shandong Fuquan Mining Co., Ltd. As raw materials, the cemented filling technology with fine-grained full tailings is investigated. Through tests analysis on the nature of tailings, tailings cementation and its slurry fluidity, the basic properties of the tailings are identified, and the appropriate types of cementitious material, the cementing process parameters and the transport conditions are determined. Meanwhile, the thickening tailings filling process is optimized.

Key words: Fine grained tailings, Cemented filling, Cementitious material, Rheological property, Tailings thickener
