Abstract: China is the largest country of lead-zinc production in the world.In 2002-2015,Chinese cumulative mine production of lead-zinc mines was 71.4 million tons,and the cumulative emission of lead-zinc tailing was about 500 million tons based on the average generation coefficient of lead-zinc mine tailing of 3.6.A good deal of discarded lead-zinc tailing not only occupy fertile lands,but also pollute the environment for a long time.It is urgent to study the utilization of lead and zinc tailing.Building materials prepared by lead-zinc tailing is an important part of its resource utilization,and remarkable achievements have been made in this area.This paper summarizes the research status and development trend of the building materials transformed from lead-zinc tailing in recent ten years in China,and then points out the existing problems and propose the solution ideas.
