In recent years, several beneficiation plants of Daye Nonferrous Metals Company have done a lot of work to improve the grade of copper concentrates, and achieved some initial results. Especially after the meeting of national nonferrous metal beneficiation held in June 1980, the spirit of the meeting was conscientiously implemented , Taking active measures, there was a marked increase in July. The average grade of copper concentrates reached 19.69% in 1980, up 5.57% from 14.12% in 1976, of which the copper oxide reached 17.35%, up from 13% in 1976 4.35%, copper sulphide reached 24.28%, higher than 15.2% in 1976 increased 9.08%. The concentrates over the years concentrate grade in Table 1.
