1. 矿产资源是人类赖以生存的重要生产资料之一, 其主要特点是不可再生和短期内不可替代性。 2. 矿产资源的开采必须经过破碎、磨矿、分选等多道工序才能选出精矿, 在此过程中必然会排出大量尾矿。 3. 世界各国每年采出的金属矿、非金属矿、煤、粘土等高达100亿t 以上, 排出的尾矿量约50 亿t , 4. 以有色金属矿山累计堆存的尾矿为例, 美国达到80 亿t , 前苏联为41 亿t 。 5. 目前我国发现的矿产有150 多种, 开发了8 000多座矿山, 累计生产尾矿59.7 亿t, 占地8 万ha 以上, 而且每年仍以3.0 亿t 的速度在增长 。 6. 尾矿不仅占用大量土地, 而且给人类生产、生活带来严重污染和危害, 现已受到全社会的广泛关注。 7. 随着矿产资源的大量开发和利用, 矿石日益贫乏, 尾矿作为二次资源再利用备受关注。 |

1. Mineral resource is one of the important means of production for human survival, its main feature is non-renewable and irreplaceable in the short term. 2. The exploitation of mineral resources must include crushing, grinding, sorting and other procedures to elect concentrates and a large amounts of tailings are inevitably discharged in this process. 3. Up to more than 10 billion tons of metal ore, non-metallic minerals, coal, clay are mined, and about 5 billion tons of tailings are discharged by various countries in the world every year. 4. For example, the accumulated stockpiles of tailings of non-ferrous metal mines in the United States and the former Soviet Union are up to 8 and 4.1 billion tons, respectively. 5. In our country, more than 150 kinds of minerals have been found and more than 8,000 mines have been developed so far, which cover an area of more than 80,000 ha, with the cumulative production of tailings of 5.97 billion tons and an annual growth rate of 300 million tons. 6. Tailings not only occupy a lot of land, but also cause serious pollution and hazards to the human production and life, it has gotten widespread concern in the whole society. 7. With the substantial development and utilization of mineral resources, minerals are becoming increasingly scarce. Therefore, recycling of tailings as the secondary resources has been of more and more concern. |
