弱磁性贫铁矿在我国丰富的铁矿资源总储量中,占有相当比重。充分利用弱磁性贫铁矿石,对钢铁工业的发展具有重要意义。建国以来,尤其是无产阶级文化大革命以来,在毛主席革命路线指引下,各有关厂矿、科研、设计部门和大专院校的广大工人、干部和技术人员,坚持“独立自主,自力更生”的方针,因地制宜,对弱磁性贫铁矿富集、分选做了大量的工作,取得了一定的成绩,在某些方面积累了丰富的经验。本期发表的鞍钢、宣钢等有关厂矿几篇经验文章,就是实例。事实说明,只要我们正确执行毛主席的革命路线和政策,依靠工人阶级,不断批判修正主义,完全可以用我国自己的力量尽快攻破弱磁性贫铁矿选矿的一些难关,为大打矿山之仗作出贡献。
Weak magnetic lean iron ore in China’s rich iron ore reserves, occupy a considerable proportion. Make full use of weak magnetic iron ore, the development of the steel industry is of great significance. Since the founding of the People’s Republic of China, especially since the Great Proletarian Cultural Revolution, under the guidance of Chairman Mao’s revolutionary line, the broad masses of workers, cadres and technicians in factories, mines, scientific research and design departments and tertiary institutions adhere to the principle of “independence and self-reliance” and according to local conditions , A great deal of work has been done on the enrichment and separation of weak magnetic iron ore and some achievements have been made. In some aspects, it has accumulated rich experience. This issue of Anshan Iron and Steel, Steel Plant, announced several experience articles, is an example. Facts show that as long as we correctly implement Chairman Mao’s revolutionary line and policies, relying on the working class and constantly criticizing revisionism, we can completely use our own power to break through some of the difficulties in beneficiation of weak-magnetic iron ore and make the battle for the fight against the mine contribution.
