关宝山铁矿赤铁贫矿的开发利用

THE DEVELOPMENT AND USENESS ABOUT HEMATITE LEAN ORE OF GUANBAOSHAN IRON MINE

关宝山铁矿的矿石赤铁贫矿占半数以上 ,由于难磨、难选 ,当年的选矿方法不过关 ,开采3年后停产。随着选矿技术的进步、精矿价格的上涨 ,开采关宝山铁矿又成为可能。关宝山铁矿紧临眼前山铁矿 ,为其建设创造了极为有利条件 ,较其它矿山更有优越条件。本文论述了开采关宝山铁矿的工艺及矿山投资情况。

More than half the ore in Guan Baoshan iron mine is hematite.As difficult to grind and choose,the choice method in that year was not succeeded,and iron mine was closed after 3 years'exploitation.With the development of the technology for choosing mine,and the rise of price for polished mine,it becomes possible to exploit Guan Baoshan Iron Mine,which next to Yan Qianshan Mine,created favourable condition compared with other mines.This article discusses the technology and the investment for exploiting Guan Baoshan Mine.
