前言我国铁矿石总储量420亿吨,其中红矿石约占四分之一,即105亿吨。我国铁矿石的另一个特点是贫矿多,富矿少,而贫矿中又是红矿比较多。这就给我国钢铁工业的发展带来了一定的困难。贫而红的矿石必需经过选矿方能在工业上加以利用。因此选矿的发展水平,往往成为铁矿石能否在工业上利用的关键。红矿比较难选,常常成为铁矿石选矿研究的重要课题。当前“攻下红矿选矿科学技术关”已列入我国长远科学规划。随着钢铁

Foreword China’s total reserves of iron ore 42 billion tons, of which about one-third of the red ore, or 10.5 billion tons. Another characteristic of iron ore in our country is that there are many lean mines, few rich mines and relatively few red mines in the poor mines. This has brought some difficulties to the development of China’s steel industry. Poor and red ore must be beneficiated to be used industrially. Therefore, the level of development of beneficiation, iron ore often become the key to the industrial use. Red ore more difficult to choose, often become an important topic of iron ore beneficiation research. At present, “attacking the red ore beneficiation science and technology” has been included in our long-term scientific planning. With steel
