随着我国钢铁工业的发展,铁矿资源中富而好选的磁铁矿日渐减少,贫而难选的红铁矿成为选矿研究和生产的主要对象之一。鉴于技术经济和环境保护的要求,近年来强磁选技术为各国广泛采用。我国自60年代末开始研制强磁选机以来,发展迅速,成果显著,特别是近几年来,由长沙矿冶研究所、沈阳选矿机械研究所和有关厂矿 With the development of China’s iron and steel industry, the rich and well-selected magnetite in iron ore resources is gradually reduced, and the poor and difficult to select red iron ore becomes one of the main targets of beneficiation research and production. In view of the requirements of technical economy and environmental protection, strong magnetic separation technology has been widely adopted in various countries in recent years. Since the late 1960s, China began to develop strong magnetic separator, the rapid development, the remarkable results, especially in recent years, by the Changsha Institute of Mining and Metallurgy, Shenyang Institute of mineral processing machinery and related factories and mines
