摘要： 硼铁矿火法分离工艺是东北大学针对辽宁地区硼铁矿的特点而开发的一项资源综合利用工艺,为定量分析该工艺流程产生的生态压力,尝试用成分法计算火法分离工业系统及各生产环节和产品的生态足迹.研究结果表明:开采加工1万t硼铁矿产生的生态足迹为2 319.302 3 hm2,其中,高炉分离环节产生的生态足迹最大,占总生态足迹的79%,最小的是选矿环节,只占1%;从产品生态足迹看,生产1万t含硼生铁产生的生态足迹最大,为7 254.984 9 hm2;利用富硼渣比利用硼精矿生产1万t硼砂产生的生态足迹小,分别为4 438.656 0 hm2和6 177.444 2 hm2;从占地类型看,主要为化石能源用地.

Abstract: A thermometallurgical separation technics was excogitated by the Northeastern University for the comprehensive resource utilization of the paigeite ore in Liaoning. To analyze the ecological pressure resulting from the process quantitatively, an attempt was made to calculate the ecological footprints caused by the whole industrial system, every link in production and products with a component-based model. The results showed that the ecological footprints caused by mining and processing every 10000t of paigeite ore are 2319.3023hm2, where the separation by blast furnace is the biggest, i.e., 79% and only 1% is caused by mineral processing. As to the products, boron-bearing iron, the ecological footprints per 10, 000t in production is up to 7254.9849hm2 which is bigger than that of the same outputs of the borax produced by either boron-rich slag or boron concentrate, i.e., 4438.6560hm2 and 6177.4442hm2, respectively. In view of the types of land occupied, the ecological footprints resulting from the utilization of fossil energy are dominant.
