Abstract: Lots of iron ore tailings are discharged into tailings storehouse in China, which caused the serious harm on environment and safety. A whole set of dry discharge process for iron tailings are explored by Shandong Coal Mining Equipment Group Co., Ltd. In this process, the tailings are classified by cyclone, where the coarser is filtered with the horizontal belt type vacuum filter, and the finer is concentrated and filtered by the completely automatic vertical filter press. The filtering cake is discharged dryly and the filtering water is recycled. A remarkable economic and social efficiency was obtained in this process.
