为了提高銅精矿的质量,減少冶煉过程中燃料的消耗及各种原材料的运輸量,并相应的提高冶煉能力和回收率,我矿最近在銅陵市委与銅矿党委的直接領导下經过一周的小型試驗,并在現場~#_1、系統进行工業生产。結果証明:銅精矿品位可以由計划的9.5%提高至15％以上,而对回收率并無多大影响,今分述如下。小型試驗部分为在現有回收率基础上,进一步將銅精矿品位提高到15～20%,在小型試驗范圍內进行了:第一次精选添加抑制剂、增加精选次数和充气試驗。試驗結果表明: In order to improve the quality of copper concentrate, reduce the consumption of fuel in the smelting process and the transportation of various raw materials, and accordingly improve the smelting capacity and recovery rate, I mine recently under the direct leadership of the Tongling Municipal Party Committee and the copper mine party After a week of small trials, and in the field ~ # _1, the system for industrial production. The results show that: copper concentrate grade can be increased from 9.5% planned to more than 15%, while the recovery rate did not have much impact, this points are as follows. In the small-scale test section, the grade of copper concentrate was further increased to 15-20% based on the existing recovery rate. The experiment was carried out in a small scale. The first time the inhibitor was added, the number of selection and the aeration test were increased. The results showed that:
