企业实行经济承包责任制以来,选矿回收率成为奖罚选矿厂完成生产任务的主要参考依据。但在具体各月中用一个固定的回收率来衡量工作的好坏,奖罚就难以合理。各月中采场的出矿品位波动较大,对选矿回收率有一定的影响。因此,作为各月的回收率是变动的,它随处理矿石品位的变化而变化。下面就我矿500吨/日选矿厂1985—1986年的实际指标,谈谈处理矿石品位与回收率的关系。(一)处理矿石品位与选矿回收率的关系我
Since the implementation of economic contract responsibility system, beneficiation recovery rate has become the main reference for the completion of the task of reward and punishment beneficiation plant. However, in a specific month with a fixed recovery rate to measure the quality of work, reward and punishment is difficult to justify. In each month, the ore field in the stope fluctuates greatly, which has a certain impact on the dressing recovery rate. Therefore, the recovery rate for each month is variable, which varies with the grade of the ore being processed. Here on my mine 500 tons / day concentrator 1985-1986 actual indicators, talk about the relationship between ore grade and recovery. (A) the relationship between processing ore grade and beneficiation recovery rate I
