In 1959, the Jilin Province Exploration Company surveyed the No. 1 rock mass Daling mining area. In 1960, it designed and constructed a 300t/d small-scale plant. It was put into operation in March 1964 and stopped production in 1972. 1967, designed by Beijing Metallurgy Design Institute of 500t / d scale beneficiation plant, put into operation in 1971, 1980 and the expansion of the concentrator, after expansion of production capacity of 1500t / d. The ore from the ore dressing is from two mining areas, 1100t/d in Fujia Mine and 400t/d in Daling Mine. After 1987, it was gradually transferred from open pit mining to underground mining. The concentrator is designed by Beijing Nonferrous Metals Design and Research Institute, and the Liaoning Metallurgical Research Institute is responsible for experimental research. Founded in 1960, it produced a production capacity of 1500t/d in 1980.
