一、选厂经济技术指标的合理选择 选矿厂所得精矿品位及回收率两者的高低虽然相互矛盾,但不成反比。尽管每个选厂的投产设计都有工艺流程试验报告作依据,但试验报告中对选矿指标好坏经常采用选矿效率评定。选矿效率只考虑技术指标,而不能反映经济效果。本文表3各指标好坏的判断如果按E_汉或E_弗计算[1],则与实际最佳的经济效益点偏离很远(则E_汉以低品位高回收率点效率最高,E_弗刚好相反)。再
First, the election of a reasonable choice of economic and technical indicators Concentrator beneficiation grade and recovery of both the level although contradictory, but not inversely proportional. Although the design of the production process for each mill has a test report based on the process, but the test report on the beneficiation indicators often used beneficiation efficiency assessment. Mineral processing efficiency only consider the technical indicators, but can not reflect the economic results. In this paper, Table 3, the indicators of good and bad judgments if calculated according to E_ Han or E_F [1], and the actual point of the best far from the point of economic benefits (E_ Han high efficiency low-grade point of the highest efficiency, E_Forg just the opposite). again
