几年来,鞍钢矿山公司一直把提高贫赤铁矿选矿技术水平作为科技攻关的重要内容,以提高企业经济效益。弓长岭选矿厂重选车间处理弓长岭矿贫赤铁矿,自1975年建成投产后,几经工艺流程改造,使生产技术指标不断提高,但由于重选工艺采用离心机丢尾,难于控制尾矿品位,致使金属回收率下降。
In recent years, Ansteel Mining Company has been raising the level of lean hematite beneficiation technology as an important part of scientific and technological research to improve the economic efficiency of enterprises. Gongchangling beneficiation plant re-election shop processing bow Changling lean hematite, put into operation since 1975, after several technological transformation, so that the production of technical indicators continue to improve, but due to re-election centrifuge throwing tail, difficult to control Tailings grade, resulting in decreased metal recovery.
