有许多铜矿选矿厂生产的铜精矿品位很低(多数在10％以下),主要是由于生产、研究与设计部门的选矿工作者当中,较为普遍的存在着一个共同看法:认为精矿品位与选矿回收率之间存在着矛盾;要得到较高的回收率,精矿品位就不容易提高,如果提高精矿品位,就势必会降低选矿回收率。因此,对这一问题未能给予应有的重视。最近苏联选矿专家聶纳罗柯莫夫同志对提高精矿品位问题提出了宝贵建议,他认为如果精矿品位提高一倍,就是回收率降低了1～3％。也是合算的,并且提
There are many copper concentrate concentrates produced at very low grades (mostly below 10%), mainly due to the common view among beneficiation workers in the production, research and design sectors that the concentrate grade There is a contradiction between recovery rate and dressing; to get a higher recovery rate, concentrate grade is not easy to improve, if you improve the concentrate grade, it will inevitably reduce the beneficiation recovery rate. Therefore, we should fail to pay due attention to this issue. Recently, the Soviet Union mineral expert Nenaluo Komov comrades to improve the quality of concentrate put forward valuable suggestions, he believes that if the concentrate grade doubled, the recovery rate is reduced by 1 to 3%. Also cost-effective, and mention
