梅山铁矿预选工艺技术改造

Technical Transformation of Preconcentration Technology of Meishan Iron Mine

对梅山铁矿选矿厂原磁重预选工艺 75～ 12mm、12～ 2mm、2～ 0mm 3个粒级在生产中存在的问题进行了分析 ,介绍了针对这些问题进行的增加 0 .5～ 0mm细粒级选别系统、更新主要选别设备、调整选别粒级范围等技术改造 。

Based on the analysis of the problems in the orignal preconcentration technology of magnetic separation and gravity separation for 75～12 mm,12～ 2 mm and 2～ 0 mm particle size fractions, technical transformation was made in view of them, which included the addition of a separation system for 0.5～ 0 mm fine particle size fraction, the renewal of main separation equipment and the regulation of particle size fraction range. Evaluation was made on the technical and economical effects of the transformation.
