用间接法计算矿石贫化率与回收率的可靠性如何?直到目前为止,在国内尚未进行过认真的分析研究,只是停留在概念上,认为间接法涉及参数多、误差大、测算化验时间长,起不到及时指导生产的作用。在国外有人分析过,认为间接法计算损失贫化率误差太大,竟可达到200～300％,即超过本身的一倍到两倍,因此认为用间接法计算损失贫化率失去意义。本文试图通过冶山铁矿的实际资料,对间接法计算贫化与回收的指标的可靠性进行精度评定。并通过分析对它存在的问题和实用价值,提
Indirect method to calculate the reliability of ore dilution rate and recovery how? Up to now, in the country has not been serious analysis, but stay in the concept, that the indirect method involves a large number of parameters, the error is large, the calculation of a long time test , Fail to timely guide the role of production. It has been analyzed abroad that the indirect method of calculating the loss of dilution rate error is too large, can actually reach 200 to 300%, that is more than double their own, so that the indirect method of calculating the loss of dilution rate of meaning. This article attempts to assess the reliability of indicators of indirect depletion and recovery based on the actual data of the Ye Shan iron ore mine. And by analyzing its existing problems and practical value, mention
