一、工业试验概况吉山铁矿位于江苏省南京市近郊,原属凤凰山铁矿所辖矿区,为产于辉石安山岩中的汽化高温热液矿床。吉山选矿厂1973年投产,采用一段湿式自磨与螺旋分级机成闭路流程。近年来随着露采逐步深入到主体矿石,硬度发生很大变化,岩石贫化率增高,自磨机台时生产能力
I. Industrial Test Overview Jishan Iron Mine is located in the outskirts of Nanjing City, Jiangsu Province, originally owned by the Fenghuangshan iron ore mines, is produced in the pyroxene andesite in the vaporization of high temperature hydrothermal deposits. Jishan concentrator put into operation in 1973, using a wet self-grinding and spiral grading machine into a closed-circuit process. In recent years, as the dew and mining gradually into the main ore, great changes in hardness, rock dilution rate increased, since grinding machine production capacity
