牟定铜矿设计为采选能力1500吨/日的中型矿山.选矿生产流程为阶段磨矿、阶段选别,即原矿经一段磨机磨至-0.074m/m占50%左右进入粗选,粗Ⅰ尾矿经第二段磨磨至-0.074m/m占80%时进行第二次粗选,粗Ⅱ尾矿再进行两次扫选,抛去最终尾矿,粗Ⅱ泡沫单独精选一次后再与粗Ⅰ泡沫合并精选两次得最终精矿.1973年至1975年单独处理郝家河中部矿段的硫化矿,平均选别指标为:原矿品位1%、实收率95.57%、精矿品位21.67%.从1976年开始,将郝家河中部硫化矿与清水河氧化矿、蟠猫氧化
Mouding copper mine designed for the mining capacity of 1,500 tons / day of medium-sized mines.Mining production process for the stage of grinding, sorting stage, that is, after a mill ore mill to -0.074m / m accounted for about 50% into the rougher, Crude Ⅰ tailings after grinding the second paragraph to -0.074m / m accounted for 80% of the second roughing, coarse Ⅱ tailings and then sweep the two sweeps, throwing the final tailings, crude Ⅱ foam separate selection Once and then combined with rough Ⅰ foam concentrate twice.From 1973 to 1975, the average ore-sorting index of sulphide ore in the central part of Haojiahe Mine was 1% of ore grade, the yield of 95.57% Ore grade 21.67% .Starting from 1976, the central part of Haojiahe sulphide ore and Qingshuihe ore, cooke oxidation
