Copper concentrate level, marking the technical level of copper. It not only directly related to product quality and economic efficiency of enterprises, but also China’s copper industry to achieve the modernization process must be addressed an important issue. In 1979, the Ministry of Metallurgy made a request to the national non-ferrous mines to make the grade of copper concentrate reach 25% within two or three years. Since the commencement of the quality month activities, the grade of copper concentrates has been increasing year by year from 18.38% to 25.22%. Among the small and medium-sized mines of the same type in China, it is second only to Langyashan Copper Mine and Tonghua Copper Mine, ranking the third Bit.
