Cemented paste backfill method has been widely used in many modern mines throughout the world due to the increasingly stringent environmental regulations and short of disposal land. This study presents experimental results on the use of Portland cement in the solidification of Pb-Zn tailings in China. Test results show UCS strength increase lineally with cement content, tailings concentration, and curing time, respectively. There exist a minimum cement content and tailings concentration to produce obvious strength. The fluidity decrease quickly with cement proportion and tailings concentration, under the satisfying of a minimum pumping fluidity, the increase of tailings concentration can effectively reduce the cement consumption so as to decrease the treatment cost.

Lead-zinc mine tailings were used to produce ceramsite by sintering method to reduce their environmental impact. The properties of tailings from Beishan Lead-zinc mine located at the north-west of Guangxi Province in southern China have been studied. The sinterability and expansion property of the main raw materials was studied during the controlled trial burn tests. The results show that lead-zinc mine tailings are not suitable for making ceramsite alone, and should be added with the clay material. The sintering temperature has a significant influence on expansion property. The optimum firing temperature to make ceramsite is from 1140 °C to 1150 °C according to the apparent density index, and the heavy metals are properly stabilized in ceramsite. It is a viable approach for making ceramsite with lead-zinc mine tailings and clay.
