摘要
鉴于鲁中冶金矿山公司现行截止品位放矿方式中存在贫化率较大的问题，提出采用提高截止品位的低贫化放矿方式，通过技术经济指标的分析计算，认为低贫化放矿技术上可行，经济上合理，在现场易于实现。
In view of the problem of greater ore dilution rate arisen from using current cut off grade drawing system,the low dilution drawing method for increase in cut off grade is put forword,and through the analysis and calculation of technical and economical index,it is considered that the low dilution drawing technique are feasibily in drawing technique,reasonable in economy,and having easy to implement and practical value.
