Fengcheng paigeite deposit is a large scale multi-metal deposit containing boron, iron and uranium, which is developed by open-pit mining, following by beneficiation (gravity separation, magnetic separation, and flotation) and hydrometallurgical treatment to obtain iron concentrate, sodium borate, and diuranate as products. In this process, several kinds of solid waste are produced such as mining waste rock, beneficiation tailing, and leached uranium tailing. Through detailed investigation of the radioactive characteristics of product and solid waste in the full process, it is indicated that iron concentrate and sodium borate meet their radioactivity quality standard. Mining waste rocks, beneficiation tailing, gravel and coarse sand produced by crushing of ore, and boron mud can be treated and disposed as ordinary solid waste other than radioactive waste. Gravel and coarse sand can be used as building materials. Boron mud is used to produce sub-nanomater silica stone without any limitation related to radioactivity, in case of the boron mud addition not exceeding 50%. Leached uranium tailing should be disposed as extremely low level radioactive waste.
