微细粒低浓度铁尾矿高效浓缩生产实践

Production Practice in High Efficient Thickening of Low-concentration Microfine Tailings from Iron Ore Dressing

介绍了鲁中矿业有限公司选矿厂微细粒低浓度铁尾矿浓缩生产现状。根据生产实践中存在的问题,对浓缩工艺进行了改进,引进了长沙矿冶研究院生产的HRC-28型高压浓缩机替代原有常规浓缩机,不仅彻底解决了微细粒低浓度尾矿的浓缩问题,而且降低了生产成本。该改进项目对同类矿山的高效浓缩具有一定的借鉴意义。

Current status of thickening operation of low-concentration microfine tailings from iron ore dressing processes in Luzhong Mining Co Ltd was introduced, and the thickening technique was optimized based on the to analysis of existing problems in on-site production. After the conventional thickener being replaced with HRC-28, a high-pressure thickener manufactured by Changsha Research Institute of Mining and Metallurgy Co Ltd, the problem of inefficient thickening of low-concentration microfine tailings has been completely solved with production cost reduced as well. This optimization practice can be used as the reference for thickening processes in mines of the same kind.
