冶金矿山每年排放的铁尾矿量是很大的。黄梅山铁矿是个地方矿山,选厂年处理氧化铁矿石仅30万吨,每年排放的铁尾矿就有22～24万吨。大量的尾矿需要建造尾矿库将其贮存起来,不仅占用众多的农田、山地,增加企业的基建投资和管理费用;若管理不善,还将污染环境,甚至危害人民生命财产。因此,综合利用尾矿,做到少排或不排尾,是我国一项重大的技术经济政策,是一个重要的研究课题。近年来,许多科研单位、大专院校开展了选矿尾矿综合利用的研究,取得了可喜的成绩。1986年,同济大学在利用黄梅山铁尾矿烧制装 The amount of iron tailings emitted from metallurgical mines each year is large. Huangmeishan Iron Mine is a local mine. The mill processes only 300,000 tons of iron oxide ore per year, and there are between 22 and 240,000 tons of iron tailings discharged each year. A large number of tailings need to be constructed tailings storage to be stored, not only occupy a large number of farmland, mountains, increase enterprise infrastructure investment and management costs; if not managed, it will pollute the environment, and even endanger people’s lives and property. Therefore, it is an important technical and economic policy in our country to comprehensively utilize the tailings so that we can make fewer or no tailings. This is an important research topic. In recent years, many research institutes, tertiary institutions to carry out the comprehensive utilization of beneficiation tailings research has made gratifying achievements. In 1986, Tongji University in the use of Huangmeishan iron tailings burning equipment
