吉山铁矿系国内极贫磁铁矿。选厂于1972年进行方案设计,次年5月第一系列建成投产。到1976年底,先后建成四个系列,设计能力为年处理原矿200万吨的湿式自磨一磁选厂。截至1982年底,自磨机共运转127,454台时,处理矿石509.33万吨,生产铁精矿88.35万吨。选厂是在边勘探,边设计,边建设的政策影响下进行建设的。投产十年来,大部分指标
Jishan Department of iron ore domestic extremely poor magnetite. Select plant in 1972 for program design, the following year in May the first series completed and put into production. By the end of 1976, it has successively built four series of wet self-grinding and magnetic separation plants with annual processing capacity of 2 million tons of ore. As of the end of 1982, a total of 5,093,300 tons of ore were processed from a total of 127,454 units of grinding machines, producing 883,500 tons of iron concentrates. The selection of plants is under the influence of exploration, design and construction of policies. Put into operation ten years, most of the indicators
