首钢矿山公司大石河铁矿为贯彻精料方针,实现磁铁精矿含铁品位65%,回收率82%(简称《65-82》,以下同),根据国外一些选厂成功应用细筛的工业实践,在学习鞍钢大孤山铁矿应用细筛提高铁精矿质量工业试验的成功经验基础上,曾就细筛作为挖潜革新技措之一。在矿党委的直接领导下,在选矿车间的具体组织下,承北京矿冶研究院、大孤山铁矿、河北矿冶学院、东北工学院各兄弟单位大力协助与支援,于1974～1977年间先后进行了一系列的试验工作,并于1977年付诸实现全厂投产使用。
Shisco Iron and Steel Company Dashihe iron ore in order to implement the principle of fine iron ore concentrate to achieve the grade of 65%, the recovery rate of 82% (referred to as “65-82”, the same below), according to some foreign successful selection of fine screening plant industry Practice, on the basis of studying the successful experience of Anshan Iron and Steel Dagushan Iron Mine fine sieve to improve the quality of iron concentrate industrial test, had fine sieve as potential innovation measures. Under the direct leadership of the mine party committee, under the concrete organization of the beneficiation plant, the Beijing Brothers and Mines Research Institute, Dagushan Iron Mine, Hebei Mining and Metallurgical Institute, and Northeast Institute of Technology strongly supported and supported each other in the period from 1974 to 1977 Has conducted a series of experimental work, and put into operation in 1977 put the plant into operation.
